Guest VM become stalled randomly on OVM 3.3.2

I upgrade my OVM to 3.3.2. Some guest VM halted without any error event.
I can't ping the guest vm. But the status is still "Running" from VM manager.
Any idea?
HP DL360 G7
Guest VM: Oracle Linux 6.6
Domain Type: XEN_PVM
BTW, I already applied patch xen-4.3.0-55.el6.22.18 as mentioned in Migration of domU broken in 3.3.2?

Oops, the vm got hang again. I can login vm through manager console. But the network is dead. The /var/log/messages from VM Server shows as follow:
Apr 28 18:05:49 ovs6 kernel: vif vif-7-0 vif7.0: txreq.offset: cfa, size: 3846, end: 7168
Apr 28 18:05:49 ovs6 kernel: vif vif-7-0 vif7.0: fatal error; disabling device
Apr 28 18:05:49 ovs6 kernel: 10ba1df20d: port 3(vif7.0) entered disabled state
After kill the vm and start it again. The log add following lines:
Apr 28 21:20:34 ovs6 kernel: 10ba1df20d: port 3(vif7.0) entered disabled state
Apr 28 21:20:34 ovs6 kernel: device vif7.0 left promiscuous mode

Apr 28 21:20:47 ovs6 kernel: ocfs2: Unaligned AIO/DIO on inode 156893450 on device dm-1 by loop0
Actually the vm should use port 2, not port 3.

Outlook Add-in becomes Inactive randomly

Hi
We have created a VSTO Add-in for Outlook. The add-in is intended as a plugin so that the other third parties can write their own "providers" that our addin can utilize. As an example the add-in shows a grid of Items. Anybody
can write a "provider" and display their own items in our grid.
To do this our add-in in made up of a three projects. core , common and library. The Library contains the public interfaces.
At run time the add-in uses MEF to load any provider assemblies.
This has been working quite successfully at numerous client sites with many users for some time. However last month a client reported that when they start Outlook the Add-in was going inactive. No attempts to re-active it would work it always
went back to inactive.
We turned on VSTO_SUPRESSDISPLAYALERTS and found that the issue seemed to be because the assemblies were not being loaded when the Add-in initialized.
Checking the assemblies that were being dynamically loaded we found that two of them were unsigned. We subsequently signed the assemblies, re-applied and everything worked.
So far so good. We patted ourselves on the back and made the assumption that some MS security Patch had been applied that stopped unsigned assemblies from being loaded at run time.
We could not however replicate the issue in house , not could we find the patch that might have caused the issue.
The problem however continues....
Our installations team took a draconian approach to this issue and started installing the signed assemblies on all our customer sites regardless of whether or not they had the original issue.
For most clients everything was fine. The add-in worked with or without the signed assemblies. However at one client site on a number of users pc's the add-in was still inactive. removing the signed assemblies and putting back the unsigned
assemblies resolved the issue. To say this is weird is an understatement. The complete opposite behavior.
Now this week they have reported another user has suddenly found the add-in is inactive and using neither the signed nor unsigned assemblies works.
We are at a complete loss what to look for next.
To summarize.
Our add-in dynamically loads assemblies at run time using MEF
It was working fine at all sites until recently.
Add-in randomly becomes inactive and cannot be re-activated either manually or through the registry.
Signing the Assemblies works at most sites
At one site unsigned assemblies work and signed assemblies do not
At the same site one user reports neither set of assemblies will activate.
We have run Caspol and cannot see anything amiss
We have used Caspol to apply Full Trust - no affect
We can not replicate in house
Things we are trying
Machine comparisons between working and non working pc's
Removal of all other add-ins
If anyone has any other suggestions what could be causing such behavior it would be much appreciated.
Nick

Hello Nick,
I do not believe the issue depends on the signed/unsigned assemblies. Check out the Trust center settings to make sure that Macro security settings are not applied to add-ins. Also pay special attention to the Trusted Publishers list.
Anyway, Microsoft Office applications can disable add-ins that behave unexpectedly. If an application does not load your add-in, the application might have hard disabled or soft disabled your add-in.
Hard disabling can occur when an add-in causes the application to close unexpectedly. It might also occur on your development computer if you stop the debugger while the Startup event
handler in your add-in is executing.
Soft disabling can occur when an add-in produces an error that does not cause the application to unexpectedly close. For example, an application might soft disable an add-in if it throws an unhandled exception while the Startup event
handler is executing.
When you re-enable a soft-disabled add-in, the application immediately attempts to load the add-in. If the problem that initially caused the application to soft disable the add-in has not been fixed, the application will soft disable the add-in
again.
You can read more about that in the
How to: Re-enable an Add-in That Has Been Disabled article in MSDN. Most probably the add-in fires an exception at runtime and Outlook disables the add-in silently.
Also pay special attention to the
Performance criteria for keeping add-ins enabled . Outlook 2013 monitors add-in performance metrics such as add-in startup, shutdown, folder switch, item open, and invoke frequency. Outlook records the elapsed time in milliseconds for each performance monitoring
metric.
For example, the startup metric measures the time required by each connected add-in during Outlook startup. Outlook then computes the median startup time over 5 successive iterations. If the median startup time exceeds 1000 milliseconds (1 second),
then Outlook disables the add-in and displays a notification to the user that an add-in has been disabled. The user has the option of always enabling the add-in, in which case Outlook will not disable the add-in even if the add-in exceeds the 1000 millisecond
performance threshold

Systems becoming "unauthenticated" randomly in network

Several of our systems will randomly have the network connection become "unauthenticated" and will loose connectivity to web pages and Office 365 through Outlook. Ping will still work and Lync remains connected for a while. The only
way to remedy is with a reboot but that is not permanent as the issue will return some time later. We have tried re-joining the domain, cycling ipconfig, flushing dns, and even changing hardware. I'm not sure what to do at this point. Any
insight would be great.

Hi Joshua,
Thanks for your reply.
we appreciate it if you could keep updating this issue.
It is possible that other software causes this kind issue.
Also try ping your Domain controller by using FQDN when this issue occurs.
Thanks

USB3 ports have become unstable - random drive dismounts (W520)

Hi,
I have a ThinkPad W520 (ThinkVantage Toolbox shows the Product as 4270CTO). About 18months old. Have been using the USB3 ports (direct, not via an external hub) to mount TrueCrypt encrypted external HDDs (Seagate GoFlex USB3.0 Slim/Ultraportable).
Worked well for 15 months or so. Last couple of months the USB ports have become unstable - dismounting the external drives randomly and then Windows pops up that irritating "You need to format the disk in drive G: before you can use it" window. Sometimes that happens two or three times in rapid succession for the same drive, over a 4 to 10 second period. Occassionally that's followed by a message in the system tray to the effect that the USB3 port has fallen back to USB2 (a message along the lines of "this drive could perform better if plugged into a USB3 port").
It's causing havoc with the encrypted filesystems - when I remount them I get a Windows prompt to scan and fix the filesystem due to the bad dismount.
Any ideas?
Regards,
JD

Update your NVIDIA drivers?
Does this workaround help?

Built-in Keyboard and trackpad become unresponsive randomly

I've been researching a lot on this but no case seems to apply to mine.
Out of nowhere, about once a day, the built-in keyboard and trackpad of my 2010 MacBook Air will stop working. The only thing that works is the power button, which brings up the power dialog in which I can't do anything. I can also do a hard shutdown.
However, if I connect an external mouse and keyboard, they work. With just a restart through them or a hard shutdown, the built-in keyboard and trackpad start working perfectly. This makes me think it's a software issue, and thinking about it, this didn't happen before 10.8.4.
I ended up resetting the PRAM, the SMC, and finally erasing my disk and reinstalling OSX. After that, I have ONLY installed Google Chrome, nothing else, and it's still happening.
I don't live in the U.S, so taking it to Apple is impossible plus the issue is not easily reproduced, not to mention the computer is almost 3 years old.
Any ideas? Thanks!

Safari 6.0.5 randomly stalls on loading pages which eventually load after hitting refresh several times. Also youtube videos will not play (blank window).

For the last few days, I've been experiencing problems with Safari 6.0.5 stalling while apparently trying to load a web page. It seems to occur randomly either when manually entering a URL address or clicking a link on a loaded web page or web search results. Using the URL bar to enter a search term is also subject to the same random stalling.
The problem is usually resolved by repeated reloads of the page (or re entering the search term or manual URL address). However the frequency with which I have to do this has become really quite annoying.
Wondering if anyone else has experienced this and knows the cause/solution?
Thanks
Toby

<edit: youtube issue resolved by uninstalling all my extensions. still testing safari to see if it continues to stall randomly>

MacPro Randomly Stalls

My MacPro stalls randomly in the middle of tasks. I have to "force quit" and then just close the force quit window and not actually force quitting an application. I have run Disk Utility countless times to repair the disks finding nothing and yet the problem continues. Can someone please shed some light on my problem? I am currently running OS 10.5.4.

Run Disk Warrior instead, don't trust Apple First Aid, it doesn't do a thorough job.
Start ruling out USB and FW devices AND cables.

Incorrect importing of photos in AP3.0.1?? Randomly renamed files? Dates?

Gday..
Been reading these threads so apologies in advance if this is covered elsewhere.. I like others upgraded from AP3.0.0 to AP3.0.1.. and initially things went well: processing sped up, Swap memory stays a manageable 1~2GB (or less). Couple of problems I am wondering if anyone else has or has found a work out for;
a) I've just imported 251 Nikon D300S RAW photos into AP3.0.1 and I go to edit them... and I get a message when I click on Inspector saying "This photo has been adjusted using a previous version of Aperture".. which is curious because I literally just finished shooting for the day. And its a new SDHC card. All I did was put the card into my SDHC Card Reader (like my other 82GB of shots) which is set to open directly into AP3.0.1... The whole "import" process seems flawed??
b) Anyone else have files that have been randomly renamed? I've got a bunch (like around 1000) that have become incomprehensible random letters? As opposed to DSC_0000 or something like that
c) Dates: You can sort your imports by date. I figure today's should be first? No. I had to go digging through 4 years of photos for today's imports.. They were literally all over the place. And my camera is CORRECTLY set up re dates etc (I just triple checked)
d) Anyone else having their Vault folder appearing suddenly under "Projects and Albums"?. Never happened under AP2..

Random page item data corruption

I designed an APEX page for a service request processing application with several date page items. Our database is Oracle 10g. The application is in production and the users have reported that data in some date page items become corrupted randomly. For example, the user enters ’07/04/2011’ in the date page item “Planned Start Date” among other values and submits the page. The date somehow winds up ‘07/04/0011’ that is, year 11. (A corrupt date increases the risk that these transactions will not be processed in a timely manner and will negatively impact the level of customer service the user wishes to provide.)
I have identified three possible areas that may hold the key to underlying cause: 1) page item edit mask, 2) page process(es), 3) DB column constraints. Inasmuch as this is a random problem and has affected a handful of rows it may not be possible to trace the logic as the pages are processed. Has anyone encountered this problem and can suggest a possible remedy? For the sake of clarity I placed the setups for the affected page item below.
Selected setups for P14_PLANNED_START_DATE, all unlisted attributes are blank or null:
Settings - Value Required: No; Format Mask: MM/DD/YYYY; Show: on icon click; Show Other Months: No; Navigation List for: None
Source - Source Used: Always, replacing any existing value in session state; Source Type: Database Column; Maintain Session State: Per session; Source Value or Expression: PLANNED_START_DATE
Default - Default Value: to_char(sysdate, ‘MM/DD/YYYY’); Default Value Type: PL/SQL Expression
Sample page processes are:
Validation - Name: P14_PLANNED_START_DATE not null; Type: Item specified is not null; Validation expression: P14_PLANNED_START_DATE; Always execute: No
Conditions – Condition Type: SQL Expression; Expression 1: :REQUEST IN (‘SAVE’, ‘CREATE’)
Validation – Name: P14_PLANNED_STARTEND_OKAY; Type: Function Returning Boolean:
Validation Expression:
IF SIGN(to_date(to_char(to_date(:P14_PLANNED_START_DATE,'MM/DD/YYYY'),'YYYYMMDD-') || :P14_PLANNED_END_TIME,'YYYYMMDD-HH:MI AM')
- to_date(to_char(to_date(:P14_PLANNED_START_DATE,'MM/DD/YYYY'),'YYYYMMDD-') || :P14_PLANNED_START_TIME,'YYYYMMDD-HH:MI AM')) > 0
THEN RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
Conditions – Condition Type: PL/SQL Function body returning Boolean
Expression 1:
IF :REQUEST IN ('SAVE','CREATE') THEN
IF (:P14_PLANNED_START_TIME IS NULL OR :P14_PLANNED_END_TIME IS NULL)
THEN RETURN FALSE;
ELSE RETURN TRUE;
END IF;
ELSE RETURN FALSE;
END IF;
Database: The attributes for the database column are
Column Name: PLANNED_START_DATE
Data Type: DATE
Nullable: No

Ligon,
You're right to think this is pretty laborious stuff. A co-worker wanted to do the same, to make sure users didn't lose a change when clicking Cancel. I suggested he look at calculating the query checksum before and after, which he tried. But it got very cumbersome very fast and he ended up dropping the idea. He's fairly new with Apex, but he's also a quick study, so it's not like he's a novice coder.
I don't have his implementation details anymore to even share with you.
Sorry I couldn't be more help.
Good luck,
Stew

OVM 3.2.1 upgrade issues

Hi all,
I have upgraded the Oracle VM manager and server from 3.0.3 to 3.2.1. OVM server and manager upgrade ran fine but the guest machine which are created using OVM 3.0.3 versions are hanging. At OVM 3.0.3 while creating a server pool, I used the same OVM server ip address instead of a new virual ip address. When I try to create a server pool with the same ip address I am getting an error like ORMRU_000044E cannot se the virtual IP address because the IP address is already in use of the server. I have tested this on development still facing the same problem. I have tried even upgrading to OVM manager and server to 3.2.2, still it is not allowing me create a server pool with the same OVM server ip address.
Please let me know if anyone faced the same problem. I have 7 different OVM 3.0.3 production servers with critical guest machines running. I used RAW disk space of the server to create the virtual machines.
Thanks
Rao

Google Mobile App & GPS work together randomly

I'm surprised we don't have a specific area for application questions, unless I missed it somewhere, however :
I'm currently back to driving a cab in the metropolitan suburbs of New York City, and often find I'm needing to know "where is the nearest "UPS" or "Dunkin Donuts" or such.
At first the Google Mobile seem to give me results knowing darn well where I was, but now I'm back to using store locaters on individual sites . . and I usually don't know what zip-code I'm in !
Did I turn something off in Settings awhile back when dealing with greater battery drain perhaps ?
GPS working in tandem w/ Google Mobile seems to have become rather random !

Please forgive a discreet bump, I can't imagine how this went to page 5 in only 2 hours !
Well.. I can imagine, I'm just astonished.

Guest Wireless Not working

Hi
I have two controllers running code 6.0.182 and one guest controller with same version.
I can see the tunnel UP(Both control and data path) in both controller.

VM live migration during OVM server upgrade

Hi Guys,
I'm planning to upgrade OVM 3.1.1 to 3.2.7.
There are 4 OVM Servers in server pool and all is using the same CPU family which means the live migration is possible.
I just wondering if I upgrade one OVM server to 3.2.7 first and then is it still available to live migrate VMs from 3.1.1. servers to new 3.2.7 server?
Thanks in advance.
Jay

Hi Jay,
I'd do the following:
- free up one OVS by migrating all guests to the remaining OVS
- upgrade OVM Manager straigh to 3.2.8
- upgrade the idle OVS to 3.2.8
- live migrate your guests from one 3.1.1 OVS to the new, idle 3.2.8 OVS - if not using OVMM, then using xm
- round robin upgrade your remaining OVS
I've done that a couple of times…
Cheers,
budy

Display wakes randomly

my display often wakes randomly from being dark (before the computer goes to sleep), and sometimes becomes bright randomly after the display has dimmed and the screensaver has come on. Does anyone have these same problems? Could this be a software issue, or does this sound like a hardware issue? Thanks

My computer did that too last night. Last night when I was sleeping the computer's brightness was all the way down and it was sleeping (the light on the open lid button was pulsing) and just randomly it wakes up, login screen open, and the brightness was all the way up. Don't know why that is happening.

Why does my guest account disable on my time capsule?

when configured for VPN with Lion Server on my mac-mini the guest account becomes inactive.
Has any one else had this problem and resolved it?

I can see them just not enable them.
Apple assumes that you will be using a simple modem with the Time Capsule.
I do not have Lion Server installed on a Mac here to be able to test, but I suspect the Time Capsule views a connection from another server differently than it would a modem.
Perhaps a user with Lion Server will be able to confirm.
