Outage followed by increase in latency

Hi BT,
The other day I experienced a short outage on my BT ADSL broadband connection after which my minimum latency has increased. Any information on what happened would be great! I am in BS6.
Here is a graph of what happened:

  • Increase in latency due to G.INP

    As a avid gamer when my ping increases it doesnt help and on the 14th of this month i noticed a increase when playing games.
    Ping to bbc.co.uk used to be in the 20ms range but now its above 30ms.
    And ispreview.co.uk seems to verify this
    If i have a huawei hg612 modem and my own router is there anyway to tell if im on G.INP without unlocking it?

    Comment from http://www.increasebroadbandspeed.co.uk/g.inp
    Someone alerted me to this yesterday, and I made a comment.
    I’ve not seen this on my line, which is currently excellent with G.INP. No increase in latency, but the connection speed improved from 74 Mbps to 80 Mbps.
    Since G.INP was enabled, I’ve not had a single error on either line.
    I’m fascinated what the issue is. Perhaps it’s the modem.

  • Latency increase with large number of databases

    Hello,
    I'm testing how BDB performs on random updates as the number of databases increases. I'm seeing increase in latency as the number of databases goes up. and strace shows that more time is spent on futex() when there are more databases. Is this an expected behavior?

    Hi James,
    Presently, we never evict a DB after it's opened or encountered during recovery. Each DB takes about 2,000 bytes. So if you have 16K DBs you need approximately 32MB of memory, assuming all of them could be opened or recovered during a process lifetime. Unfortunately, even closing them does not cause them to be evicted. If you encounter them during recovery, this will also pull them into memory.
    We have an FAQ entry on this:
    http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#37
    So you will need a bigger cache size. If you are encountering this during recovery, then you could try a more frequent checkpoint interval.
    I hope this is useful.
    Regards,
    Charles Lamb

  • Another case of intermittent internet outages

    For approximately the past 2 months, we have been experiencing periodic outages of our internet connectivity lasting minutes to hours.  Based on ongoing logging of ping times to www22.verizon.com, these episodes last for minutes to hours and are frequently preceded by periods of increasing network latency.  These episodes only affect the connection to the internet whereas connections within the house (between computers/devices/printers) remain completely functional with no latency. This is also NOT a WiFi problem as the connectivity to the internet affects computers connected via ethernet and WiFi the same.
    Turning the Actiontec off and back on restored internet connectivity some of the time.
    More recently, I tried disconnecting and reconnecting the coax from the ONT to the Actiontec and that reliably restores internet connectivity.
    At no point have either the ONT or router shown an error condition (all lights are green).
    There has been nothing in the Actiontec logs that suggested an error on the part of the router.
    We have about 16 devices on the network and all of those that access the internet are affected the same (Mac laptops, Windows laptop, Mac desktop, Linux-based HTPC, 2 phones, iPad, iPod, Wii, TV, Blu-Ray.)
    As I mentioned, we have been monitoring the connection using Cacti (www.cacti.net) to characterize the outages and they occur as described (usually increased latency followed by an outage). Based on these logs, the episodes only occur when we are actively using the network - i.e., not in the middle of the night or middle of the day on week days when no one is at home.
    We have contacted Verizon about 8 times regarding this problem without resolution.  This has included 3 separate visits by technicians to the house.  Here is what has been tried so far:
    Reset of the router to system defaults - no help.
    Use of alternative DNS servers on the router - no help.
    Replacement of the router with a new model (MI424-WR rev. F, original was rev. C) - no help.
    At the second visit by a Verizon technician, the ONT and its power supply were replaced - no help.
    Also at the second visit, the technician contacted Tier 2 support and the voice on the phone mentioned that he could see errors on some piece of Verizon hardware and that he would "monitor" the connection but this did not solve the problem.  Verizon makes it very hard, if not impossible, to contact Tier 2 support by calling Tier 1 support so we had no way to follow up with Tier 2 to let them know that nothing was resolved - no help.
    The third technician visit was supposed to include a "supervisor" (but did not) and resulted in no new ideas - no help.
    In an effort to avoid a conversion back to Comcast (after ~5 years of otherwise great service with FiOS), I purchased a new Netgear router and set up the Actiontec as a bridge (http://www.dslreports.com/forum/r17679150-Howto-make-ActionTec-MI424WR-a-network-bridge) - no help.
    After all of this, I am convinced that the problem lies somewhere with Verizon but don't know how to get them to do a more thorough evaluation.  I base this on the fact that we never lose connectivity within the house and that even configuring the Actiontec as a bridge did not have any effect.
    This problem (or one like it) has been described several times in these forums (search "intermittent" under FiOS Internet) and only some of those have been resolved.  Of those that have been resolved, none apply as we have tried all of the things that worked for them.
    I do not relish the thought of having to make the conversion back to Comcast so I am hopeful there may be some wisdom in this group about how to diagnose and resolve this.
    Thank you for your time.

    When there is no connectivity, the trace stops at the router or we are unable to resolve the host name.

    Thansk fro the link but all you did was provide me the live chat support link, which I have already done. I have already contacted Verizon and they have replaced the Router and tomorrow they come to troubleshoot the ONT, but I dont believe the problem lies within my house, as I think the problem exists on the FIOS network outsike my home.
    Please assist in getting my case escalated with FIOS support.

  • Query latency vs number of partitions

    I am trying to measure the average latency per object retrieval using the query approach, and what I am finding is that as the number of instances of the server (a server being a single jvm running DefaultCacheServer with backup-count set to 1, and partition-count set to 1021) increases, the latency increases significantly as shown in the results below:
    Latency (microseconds) for Number of server instances
    Objects 2 4 8 16
    In Cache srvrs srvrs srvrs srvrs
    1K 593 730 889 1175
    10K 592 720 880 1206
    50K 580 724 879 1200
    100K 585 726 877 1204
    The query code is as follows:
    final Filter filter = new EqualsFilter(idExtractor, key);
    final Filter limitedFilter = new LimitFilter(filter, 1);
    final Set spotPricesKeys = cache.keySet(limitedFilter);
    if (spotPricesKeys != null && spotPricesKeys.size() > 0){
         spotPrice = (SpotPrice) cache.get(spotPricesKeys.iterator().next());
    and
    private static ValueExtractor idExtractor = new KeyExtractor("intValue");
    Any idea why the latency is increasing with the added number of server instances?
    Thanks

    Partitioning strategies is an "advanced" feature of Coherence. It works much like a hash function but instead of a hash code it calculates the partition number that will be used for each key. You can use more or less any deterministic algorithm based only on key information. Lets assume that you have a cache with strings as keys (representing for instance a persons name) and you would like to partition based on the first letter it could look something like this (this is just an example - in production code you would like to make sure the algorithm statistically makes as even use of all the partitions that you have in your cluster!):
    public class MyPartitionStrategy implements KeyPartitioningStrategy, Serializable {
    private PartitionedService partitionedService;
    public MyPartitionStrategy() {
    public void init(final PartitionedService partitionedService) {
    this.partitionedService = partitionedService;
    public int getKeyPartition(final Object key) {
    if (key instanceof String) {
    return ((String) key).charAt(0) % (partitionedService.getPartitionCount() + 1);
    } else {
    return key.hashCode() % (partitionedService.getPartitionCount() + 1);
    With this filter you would know that all keys starting with the same first letter ends up in the same partition. You would specify the use of this filter once in the coherence configuration (dont remember the element to use on top of my head though).
    Now assume that you for some reason want to do some query that only should apply to entries with a key starting with the letter 'a' you could do that with a PartitionedFilter (you would have to write some code that determines what partition the key 'a' would end up if it existed and then restrict the query to that single partiton). With this solution Coherence will only send the request to the single node holding the primary for that one partition holding all the "axxxx" keys and not to all the nodes in the cluster making the query scale close to linerary no matter how many nodes you have!
    A problem when the number of partitions grow is to find a partitioning strategy that allocates a useful set of objects into a single partition. If you for instance have like 4000+ partitions and would like to divide addresses based on state in order to perfrom queries against all of your customers in a particular state there is no obvious way to do that since the number of states is much smaller than the number of partitions :-(
    This kind of partitioning can however be very useful in many cases (we have used it to good effect in my current project).
    In produktion code it is often some part of a composite key that is useful as a key partitioning criteria and you could then for instance return the standard hash code of that key part modulus he partition count.
    Another possibly useful feature you may look at is when it comes to limiting the number of nodes invloved in queries is the KeyAssociatedFilter (if you use key association at all in your cache).

  • How do I increase the font size in my email and maintain resolution.

    Hi folks. Mr Newbie is seeking some help, I hope it is relatively straight forward, thanks
    How do I increase the font size in my standard email and document views without losing resolution.  Right now my font size in email, headers and text is less than that on my iPhone, it rather defeats the point of having a 27" screen if most of it is blank and I have to sit with my nose to the screen to read email.  Thanks for your help, once you have stopped laughing.  C

    Two things you can do to easily aid with readability in Mail are as follows:
    1) Increase the size of folders in the sidebar:
    a) select "system preferences" from the Apple menu
    b) select "general settings"
    c) select small, medium or large under "sidebar icon size"
    2) Increase the text in the main body of the email (both sent and received):
    a) select "preferences" from the Mail menu
    b) select "fonts and colors"
    c) adjust font size for "message list font" and "message font".  I have noticed this works properly while in classic mode, but in regular mode the message list font doesn't appear to change size.
    Select classic mode by accessing Mail preferences and selecting the "viewing" tab.
    Another shortcut is to right click on the toolbar, then select "customize toolbar", and then drag the "smaller / bigger" buttons onto the toolbar.  Now you can decrease and increase font size as desired on the fly.

  • Increase value of PO assigned to an Asset which has been set by A/P

    Hello experts,
    We need to increase the value of a PO which is assigned to an OA. There are two things that complicate this:
    1.- The vaue to which PO needs to be increased is over the one specified in the OA.
    2.- The asset, to which the PO is assigned, has been set by A/P during the PO creation process.
    Is there any chance to increase the PO value?
    I think we need to do the following:
    1)    Increase the OA.
    2)    Have A/P increase the Booked Asset Value? If not the asset valuation would be incorrect.
    3)    Then increase the PO as requested.
    We would really appreciate any help relating this issue.
    Thank you very much in advanced to you all!

  • Increase 'archive_max_process'  in oracle 10g

    Dear Friends ,
    I want to increase the value of 'archive_max_process' dynamically (i.e., alter system or alter database ) in my oracle 10g . Is it possible to do ?

    Hi,
    Kindly find the below.
    alter system set log_archive_max_processes=4;
    The LOG_ARCHIVE_MAX_PROCESSES initialization parameter specifies the number of ARCn processes that the database initially invokes. The default is two processes. There is usually no need specify this initialization parameter or to change its default value, because the database starts additional archiver processes (ARCn) as needed to ensure that the automatic processing of filled redo log files does not fall behind.
    However, to avoid any runtime overhead of invoking additional ARCn processes, you can set the LOG_ARCHIVE_MAX_PROCESSES initialization parameter to specify up to ten ARCn processes to be started at instance startup. The LOG_ARCHIVE_MAX_PROCESSES parameter is dynamic, and can be changed using the ALTER SYSTEM statement. The database must be mounted but not open. The following statement increases (or decreases) the number of ARCn processes currently running:
    ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=3;

  • Network Round Trips when loading a Form - reducing Network Latency

    I am working on a Forms migration from Client-Server to WebForms running on Application Server 10.1.2.0.2
    Does anyone know the minimum number of network round trips that can be achieved when loading a Form?
    For most of the Forms in the migration I am seeing 3 network round-trips before the Form is displayed and on Forms that use Webutil I am seeing 7 round-trips before the Form is displayed. Is this normal or are there ways of optimizing the round-trips down?
    The Forms code has already been optimized by removing SYNCHRONIZE commands and TIMER commands and I have already refered to metalink note 363285.1 which gives lots of good advice however there is no specific information on the minimum number of round trips that you can expect for loading a Form.
    Thanks for any help you can give.
    Philippe

    Ok, a bit of an update is needed.
    There were a number of posts below that have been lost due to an accidental deletion but I shall try and summarize them here:
    Tony Garabedian - Posted a number of code optimizations that he'd used for speeding up code when querying within a Form. Tony if you are able to re-post those that would be great :-)
    Grant Ronald - posted some more information in which he mentioned that the extra pings are used to synchronize between the App.Server and the client. He also commented that a network that uses satellite was inherently slower and would therefore require a different front end to handle the increase in latency.
    For my part I said nothing new other than ask loads more questions. I did mistakenly comment that we are using satellite for our network however upon yet more discussion with our network guy it turns out that we're using optical cable for everything. Out guaranteed round trip time is about 320 milli-seconds to Australia from the UK.
    Currently I am left with the understanding that we are not likely to go below 3 round trips for most of our Forms and in the case of Webutil we are likely to be limited to 7 round trips.
    Of course if anyone out there has any specific experience with this issue and can comment further please feel free.
    Many thanks,
    Philippe

  • Reader: any way to increase the width?

    I love Safari's Reader function...I just wish it took up a wider portion of the screen.   Currently, the text itself, not including the margins of the "paper", takes up less than 50% of the screen width.
    I know the answer is NO, but thought I'd ask anyway...

    This was a little time consuming but not too difficult. Unless somebody knows of a better way you might like to try the following.
    Go to /Applications/Safari.app/Contents with 'Go To Folder' - on Finder Go menu
    Put alias of Resources folder onto Desktop - highlight / cmd L and then drag
    Close Contents folder
    Double click alias and highlight Reader.html then hit cmd D to duplicate it as a backup
    Open original Reader.html with Safari and 'View as source'
    Select all (cmd A) and copy / paste into new TextEdit document
    Quit from Safari
    Copy and paste the following onto new lines just before </style>
    /* The following modification increases width by 300px. */
    #container { margin-left: -581px; width: 1162px }
    #drop-shadow { width: 1100px }
    #article { width: 1119px }
    .article-fade { width: 1100px }
    .page { width: 958px }
    Save to Desktop as Reader.html
    Option drag Desktop version of Reader.html onto alias to replace original
    Start Safari and test
    Good luck.

  • Increased download speed = increased ping

    Hi,
    After some wrestling of biblical proportions with BT Technical and having had 5 engineers out since January a faulty section of cable was replaced last week. This has led to three changes in our broadband service, two good, one very bad.
    1. The download speed increased from around 0.98 mb/s to 2.10 mb/s - Great.
    2. Incoming phone calls no longer caused the broadband connection to reset - Great.
    3. The ping has increased from a steady 48ms to 96ms - Bad.
    For info I have a Home Hub 3 with Option 3 package and the above numbers came from www.speedtest.net. This issue is of particular annoyance with XBox-Live which is now virtually unusable following the increase in ping. The XBox is set up for port forwarding and in the DMZ and is connected to the hub through an official wireless adaptor.
    Any assistance with this would be much appreciated.
    Thanks
    Chris

     I see you are still online while you are waiting try the command prompt ping-The easiest way to check ping is to open the Command Prompt on the PC and type "ping (ip Address or Website)". Example:
    ping www.google.com
    I take it your PC is wired!

    I am currently using a motion system which has been neglected for a while due to some shortcomings for the original application.
    I'm trying to revive it by making use of the following error to detect when contact is made between two objects.  The main Problem I have is reducing the contact pressure in such an arrangement.  I have implemented a basic version where the axis moves until the following error goes above a certain value (say 30 = 30um) upon which the axis then stops.
    The problem is that I'd like to choose a much smaller value, but the jitter is too large to allow this.  I get values anywhere between 0 and 20 while the axis is moving.  Of course the following error increases dramatically once contact is made, but the problem is detecting this contact point quickly enough so that the pressure created is as low as possible.
    I've tried limiting the torque of the servo motors, but I'm not sure this has had an effect.
    Does anyone have an idea what I can change to improve this apart from using a different algorithm to detect smaller changes of the following error (slope over the last 10 measurements or something)?  Do I need to modify the coupling between the motor and the axis?
    Thanks
    Shane.
    PS, I have already got some micrometer switches hooked up to the hardware, and they work nicely, but the ACTUAL contact points between two non-micrometer switches is what I'm after.

    Jochen,
    Thanks for the answer.
    I've tried testing it with a 1mm glass substrate between the axis head (flat steel surface) and the stage (also flat steel surface) so that the two steel surfaces are slightly tilted to each other (representing what I hope is a real-world scenario).
    I can drive the axis with 5 RPM (enough for my application) and a permitted following error of up to 2000 without breaking the glass.  I think this already gives me enough information to continue.  Incidentally, the rising flank of the following error curve versus position allows me to work out the exact point of contact afterwards, thus giving me the required accuracy.
    I think the clue to all this is the way the axis is coupled to the motor.  I reckon this is absorbing a certain amount of tracking error and as long as I don't drive the axes together with great speed os allow a huge following error, things should be fine.  I think I'll use 60 or 100 as my limit, then things should be OK.
    A lot depends also on HOW the surfaces come into contact.  Edge on edge will break most things, but as long as they're more or less parallel to each other, the tolerance seems to be quite a bit higher than I originally thought.
    Thanks again.
    Shane.

  • [Solved] No sound (using Gnome with Pulseaudio)

    Hello,
    I have an issue with my audio. Since yesterday it has not been working, as in no sound in my headphones
    I updated gnome, cinnamon and linux yesterday. I did not however update pulseaudio or anything else alsa related (as far as I can tell).
    Another possible cause could be switching from cinnamon to gnome which I did yesterday (I don't know when exactly my audio stopped working).
    Other relevant facts:
    -My mic is still working fine
    -Using the Xonar DG sound card
    -Nothing is muted in alsamixer
    -not a hardware issue, working fine in dual boot windows
    Pulse audio in verbose mode suggest that the issue is not pulseaudio (as does pavucontrol's visualization):

    My best guess at this point is that something(tm) is wrong with alsa. I have no idea how to troubleshoot this though. Any advice?
    Please let me know if anything important is missing.

    Did you ever have a copy of front channels or a mix of all of them played on the headphone jack with alsa only? I doubt it. If you kill pulseaudio and run following, what channels do you hear from headphones?
    speaker-test -c 8 -t wav -D plughw:DG,0
    This is probably more of a pulseaudio issue, since alsa usually does not copy streams.
    InfamousBlue wrote:I did not however update pulseaudio or anything else alsa related (as far as I can tell).
    Partial upgrades are not supported. There are some remapping examples on the wiki. If you seek a hardware remapping solution try hdajackretask from alsa-tools, it works however for hda compliant cards.

  • VMQ issues with NIC Teaming

    Hi All
    Apologies if this is a long one but I thought the more information I can provide the better.
    We have recently designed and built a new Hyper-V environment for a client, utilising Windows Server R2 / System Centre 2012 R2 however since putting it into production, we are now seeing problems with Virtual Machine Queues. These manifest themselves as
    either very high latency inside virtual machines (we’re talking 200 – 400 mSec round trip times), packet loss or complete connectivity loss for VMs. Not all VMs are affected however the problem does manifest itself on all hosts. I am aware of these issues
    having cropped up in the past with Broadcom NICs.
    I'll give you a little bit of background into the problem...
    Frist, the environment is based entirely on Dell hardware (Equallogic Storage, PowerConnect Switching and PE R720 VM Hosts). this environment was based on Server 2012 and a decision was taken to bring this up to speed to R2. This was due to a number
    of quite compelling reasons, mainly surrounding reliability. The core virtualisation infrastructure consists of four VM hosts in a Hyper-V Cluster.
    Prior to the redesign, each VM host had 12 NICs installed:
    Quad port on-board Broadcom 5720 daughter card: Two NICs assigned to a host management team whilst the other two NICs in the same adapter formed a Live Migration / Cluster heartbeat team, to which a VM switch was connected with two vNICs exposed to the
    management OS. Latest drivers and firmware installed. The Converged Fabric team here was configured in LACP Address Hash (Min Queues mode), each NIC having the same two processor cores assigned. The management team is identically configured.
    Two additional Intel i350 quad port NICs: 4 NICs teamed for the production VM Switch uplink and 4 for iSCSI MPIO. Latest drivers and firmware. The VM Switch team spans both physical NICs to provide some level of NIC level fault tolerance, whilst the remaining
    4 NICs for ISCSI MPIO are also balanced across the two NICs for the same reasons.
    The initial driver for upgrading was that we were once again seeing issues with VMQ in the old design with the converged fabric design. The two vNics in the management OS for each of these networks were tagged to specific VLANs (that were obviously accessible
    to the same designated NICs in each of the VM hosts).
    In this setup, a similar issue was being experienced to our present issue. Once again, the Converged Fabric vNICs in the Host OS would on occasion, either lose connectivity or exhibit very high round trip times and packet loss. This seemed to correlate with
    a significant increase in bandwidth through the converged fabric, such as when initiating a Live Migration and would then affect both vNICS connectivity. This would cause packet loss / connectivity loss for both the Live Migration and Cluster Heartbeat vNICs
    which in turn would trigger all sorts of horrid goings on in the cluster. If we disabled VMQ on the physical adapters and the team multiplex adapter, the problem went away. Obviously disabling VMQ is something that we really don’t want to resort to.
    So…. The decision to refresh the environment with 2012 R2 across the board (which was also driven by other factors and not just this issue alone) was accelerated.
    In the new environment, we replaced the Quad Port Broadcom 5720 Daughter Cards in the hosts with new Intel i350 QP Daughter cards to keep the NICs identical across the board. The Cluster heartbeat / Live Migration networks now use an SMB Multichannel configuration,
    utilising the same two NICs as in the old design in two isolated untagged port VLANs. This part of the re-design is now working very well (Live Migrations now complete much faster I hasten to add!!)
    However…. The same VMQ issues that we witnessed previously have now arisen on the production VM Switch which is used to uplink the virtual machines on each host to the outside world.
    The Production VM Switch is configured as follows:
    Same configuration as the original infrastructure: 4 Intel 1GbE i350 NICs, two of which are in one physical quad port NIC, whilst the other two are in an identical NIC, directly below it. The remaining 2 ports from each card function as iSCSI MPIO
    interfaces to the SAN. We did this to try and achieve NIC level fault tolerance. The latest Firmware and Drivers have been installed for all hardware (including the NICs) fresh from the latest Dell Server Updates DVD (V14.10).
    In each host, the above 4 VM Switch NICs are formed into a Switch independent, Dynamic team (Sum of Queues mode), each physical NIC has
    RSS disabled and VMQ enabled and the Team Multiplex adapter also has RSS disabled an VMQ enabled. Secondly, each NIC is configured to use a single processor core for VMQ. As this is a Sum of Queues team, cores do not overlap
    and as the host processors have Hyper Threading enabled, only cores (not logical execution units) are assigned to RSS or VMQ. The configuration of the VM Switch NICs looks as follows when running Get-NetAdapterVMQ on the hosts:
    Name                           InterfaceDescription             
    Enabled BaseVmqProcessor MaxProcessors NumberOfReceive
    Queues
    VM_SWITCH_ETH01                Intel(R) Gigabit 4P I350-t A...#8 True    0:10             1            
    7
    VM_SWITCH_ETH03                Intel(R) Gigabit 4P I350-t A...#7 True    0:14             1            
    7
    VM_SWITCH_ETH02                Intel(R) Gigabit 4P I350-t Ada... True    0:12             1            
    7
    VM_SWITCH_ETH04                Intel(R) Gigabit 4P I350-t A...#2 True    0:16             1            
    7
    Production VM Switch           Microsoft Network Adapter Mult... True    0:0                           
    28
    Load is hardly an issue on these NICs and a single core seems to have sufficed in the old design, so this was carried forward into the new.
    The loss of connectivity / high latency (200 – 400 mSec as before) only seems to arise when a VM is moved via Live Migration from host to host. If I setup a constant ping to a test candidate VM and move it to another host, I get about 5 dropped pings
    at the point where the remaining memory pages / CPU state are transferred, followed by an dramatic increase in latency once the VM is up and running on the destination host. It seems as though the destination host is struggling to allocate the VM NIC to a
    queue. I can then move the VM back and forth between hosts and the problem may or may not occur again. It is very intermittent. There is always a lengthy pause in VM network connectivity during the live migration process however, longer than I have seen in
    the past (usually only a ping or two are lost, however we are now seeing 5 or more before VM Nework connectivity is restored on the destination host, this being enough to cause a disruption to the workload).
    If we disable VMQ entirely on the VM NICs and VM Switch Team Multiplex adapter on one of the hosts as a test, things behave as expected. A migration completes within the time of a standard TCP timeout.
    VMQ looks to be working, as if I run Get-NetAdapterVMQQueue on one of the hosts, I can see that Queues are being allocated to VM NICs accordingly. I can also see that VM NICs are appearing in Hyper-V manager with “VMQ Active”.
    It goes without saying that we really don’t want to disable VMQ, however given the nature of our clients business, we really cannot afford for these issues to crop up. If I can’t find a resolution here, I will be left with no choice as ironically, we see
    less issues with VMQ disabled compared to it being enabled.
    I hope this is enough information to go on and if you need any more, please do let me know. Any help here would be most appreciated.
    I have gone over the configuration again and again and everything appears to have been configured correctly, however I am struggling with this one.
    Many thanks
    Matt

    Hi Gleb
    I can't seem to attach any images / links until my account has been verified.
    There are a couple of entries in the ndisplatform/Operational log.
    Event ID 7- Querying for OID 4194369794 on TeamNic {C67CA7BE-0B53-4C93-86C4-1716808B2C96} failed. OidBuffer is  failed.  Status = -1073676266
    And
    Event ID 6 - Forwarding of OID 66083 from TeamNic {C67CA7BE-0B53-4C93-86C4-1716808B2C96} due to Member NDISIMPLATFORM\Parameters\Adapters\{A5FDE445-483E-45BB-A3F9-D46DDB0D1749} failed.  Status = -1073741670
    And
    Forwarding of OID 66083 from TeamNic {C67CA7BE-0B53-4C93-86C4-1716808B2C96} due to Member NDISIMPLATFORM\Parameters\Adapters\{207AA8D0-77B3-4129-9301-08D7DBF8540E} failed.  Status = -1073741670
    It would appear as though the two GUIDS in the second and third events correlate with two of the NICs in the VM Switch team (the affected team).
    Under MSLBFO Provider/Operational, there are also quite a few of the following errors:
    Event ID 8 - Failing NBL send on TeamNic 0xffffe00129b79010
    How can I find out what tNIC correlates with "0xffffe00129b79010"
    Without the use of the nice little table that I put together (that I can't upload), the NICs and Teams are configured as follows:
    Production VM Switch Team (x4 Interfaces) - Intel i350 Quad Port NICs. As above, the team itself is balanced across physical cards (two ports from each card). External SCVMM Logical Switch is uplinked to this team. Serves
    as the main VM Switch for all Production Virtual machines. Team Mode is Switch Independent / Dynamic (Sum of Queues). RSS is disabled on all of the physical NICs in this team as well as the Multiplex adapter itself. VMQ configuration is as follows:
    Interface Name          -      BaseVMQProc          -        MaxProcs         
    -      VMQ / RSS
    VM_SWITCH_ETH01                  10                             
         1                           VMQ
    VM_SWITCH_ETH02                  12                              
        1                           VMQ
    VM_SWITCH_ETH03                  14                               
       1                           VMQ
    VM_SWITCH_ETH04                  16                              
        1                           VMQ
    SMB Fabric (x2 Interfaces) - Intel i350 Quad Port on-board daughter card. As above, these two NICs are in separate, VLAN isolated subnets that provide SMB Multichannel transport for Live Migration traffic and CSV Redirect / Cluster
    Heartbeat data. These NICs are not teamed. VMQ is disabled on both of these NICs. Here is the RSS configuration for these interfaces that we have implemented:
    Interface Name          -      BaseVMQProc          -        MaxProcs       
      -      VMQ / RSS
    SMB_FABRIC_ETH01                18                                   2                           
    RSS
    SMB_FABRIC_ETH02                18                                   2                           
    RSS
    ISCSI SAN (x4 Interfaces) - Intel i350 Quad Port NICs. Once again, no teaming is required here as these serve as our ISCSI SAN interfaces (MPIO enabled) to the hosts. These four interfaces are balanced across two physical cards as per
    the VM Switch team above. No VMQ on these NICS, however RSS is enabled as follows:
    Interface Name          -      BaseVMQProc         -         MaxProcs      
       -        VMQ / RSS
    ISCSI_SAN_ETH01                    2                                    2                           
    RSS
    ISCSI_SAN_ETH02                    6                                    2                           
    RSS
    ISCSI_SAN_ETH03                    2                                   
    2                            RSS
    ISCSI_SAN_ETH04                    6                                   
    2                            RSS
    Management Team (x2 Interfaces) - The second two interfaces of the Intel i350 Quad Port on-board daughter card. Serves as the Management uplink to the host. As there are some management workloads hosted in this
    cluster, a VM Switch is connected to this team, hence a vNIC is exposed to the Host OS in order to manage the Parent Partition. Teaming mode is Switch Independent / Address Hash (Min Queues). As there is a VM Switch connected to this team, the NICs
    are configured for VMQ, thus RSS has been disabled:
    Interface Name        -         BaseVMQProc        -          MaxProcs       
    -         VMQ / RSS
    MAN_SWITCH_ETH01                 22                                  1                          
    VMQ
    MAN_SWITCH_ETH02                 22                                  1                           VMQ
    We are limited as to the number of physical cores that we can allocate to VMQ and RSS so where possible, we have tried balance NICs over all available cores where practical.
    Hope this helps.
    Any more info required, please ask.
    Kind Regards
    Matt
