Server connection: drops and disk errors

Currently, I'm the only workstation using a Mac Pro (the rest are G5s), and my connection to our art server (running Win 2003) constantly drops, whereas the G5s stay connected just fine. Also, today this same server started giving me code -41 disk error messages; I can't save or re-write anything onto the server, even though there's a good 20GB of storage available.

John,
We lost the connection earlier this evening, and even though the lights were all still on on the Router, the only way to regain our connection seemed to be turning the router off and on (we did this at the plug, i'm not sure this is what we're meant to do!).
Are the events in my event log worrying at all? I'm scared by them!

Wireless connection drops and doesn't reconnect (netcfg, wpa_actiond)

I use netcfg 2.5.4-1 and wpa_actiond 1.1-1, B43 driver (BCM4318 wireless card) with firmware.
$ uname -a
Linux vekta 2.6.32-ARCH #1 SMP PREEMPT Mon Mar 15 20:08:25 UTC 2010 i686 Mobile AMD Sempron(tm) Processor 3100+ AuthenticAMD GNU/Linux
Connecting works fine. I can connect using sudo netcfg <profile>, or it automatically connects me on startup.
However, after a few minutes (up to 15 at best, usually 3-5) the connection is dropped. dmesg prints:
"No probe response from AP <macaddress> after 500ms, disconnecting."
However, netcfg isn't notified of this event, and still thinks the profile is connected. So I have to use netcfg -r <profile> to reconnect. Isn't netcfg supposed to notice this connection drop and try to reconnect again automatically?
Also, is there any way to increase the 500ms threshold mentioned in the log? I don't think I ever had this problem when I first installed arch in november/december last year.
Thank you.

Hey,
I'm having this sort of problem with my Broadcom wireless card, in my case however the connection seems to drop after a period of inactivity. What you have done might solve my problem. So exactly what modification have you made in netcfg ?

Ongoing Broadband connection drops and slow speed ...

Over the last few weeks i seem to be having random issues with my Broadband connection and teh connection has become very unstable and unreliable
The connection will randomly drop and re-establish, often at a much lower speed that it should be. I regularly get around 3 - 4MB download speed which is good for my area but often find that when it reconnections i get around 1MB. To resolve the issue i usually have to restart my hub (BT HH2) which then usually gets me back to the normal speed.
Luckily I do have a SamKnows box which shows this issue in a graphical form. Note how unstable the connection and speed seems to be! Surely it is not be like this?

All line tests i have done come back clean and there is no noise on the line.
Any ideas please?

ok so i plugged my HH2 in to the test socket as suggested and today have found the connection to be more unstable than usual.... So around 45 minutes ago the connection drops and re-establishes and i get the below results:

Difference between using app server connection pooling and using the driver

Hi all,
How to get connection pooling with out application server and tomcat also?
What is the difference between using app server connection pooling and using the driver supported connection pooling?
Regards,
Murali

maybe the performance of App server pool is better than the JDBC pool,
for you don't know wether the implementation of the JDBC interface is good or bad.

BT Wi-Fi connection drops and cannot be closed

I use BT Wi-Fi on a monthly subscription - 500 minutes for £6 a month, plus 12p a minute for any extra minutes.
Occasionally my connection drops, and I have to reconnect and login again, which I can do OK.
But when I check later how many minutes I used, via my online subscription info, it's clear that I end up with two connections running in parallel. The connection which dropped carries on as active in the background somewhere until it is eventually auto-disconnected (after 15 or 20 minutes ?) due to inactivity. So I lose those minutes each time this happens.
There is no way to close the dropped connection. Even if I log out of my new 2nd connection, it only closes that one, not the dropped one which I can't access.
Today this happened when I was at the end of my monthly allowance, so because I couldn't close the connection I've now gone around 30 minutes over my allowance, which will cost me £3.60.
Please can we have a way of closing all connections on a BT Wi-Fi account, to deal with this issue.
And a refund would be good, as I had no way of preventing my account going into the 12p a minute rate.

Frequent SNR drops and high error rates

Heya all,
As of the past few days, I've been having issues with my BT Infinity 2 connection suffering from long periods where the SNR drops, and error rates increase. I've contacted support on the phone, but sadly unless I'm using a Home hub, they won't help me, and I don't have one to use. I've offered to provide them with any information they require by email, but they say it's not possible to send them anything. They've tried several line tests and they insist that everything is fine with the line, and that I must have faulty hardware on my end.
For a bit of history; I've had this connection since March 2012. When it was first set up, I was getting no interleaving down or up, and I was getting over the 40/10 I was quoted. A few months later, I was given an upgrade to 80/20. The interleaving remained at 0 both directions, and latency was around 12ms to bbc.co.uk (as an example). As time went on, errors began to show in my modem logs, the speed began to drop, interleaving kicked in, and the latency has increased. I called them about it originally, and an engineer came out. They replace the face plate, gave us a new modem, and issues an line reset. This solved the problem completely for a few months. Around 2 months later, the same things began to happen again. I called support again, but this time, I was outside of my contract period, so they effectively refused to help unless I was using their Home Hub thing, and blamed my equipment. Since this last call, things have steadilly got worse, until recently when the SNR drops began to occurr...
All I want is my connection how it was when I first changed to 80/20, with no interleaving. Nothing has changed in my flat since the connection was installed. There have been issues with street lighting and roadworks in the past, but I believe these were resolved. I suspect that there is a fault with either our line down to the distribution box downstairs (BT's responsibility) or the wire from there to the cabinet (Ashton-under-Lyne, Cabinet 6) (also BT's responsibility). I would ask for an engineer to come out, but I know they won't find a problem (even though there is clearly one there) and I'll get charged for a call-out, and still have my problem! What can I do to try and get it back to how it was?
Asn additional note, there's a neighbor of mine around the corner who's got the same product, going to the same cabinet, and they don't have any of these problems.
This is the current state of my connection as of 2014/07/17 09:47:35:
http://brins0.net:5555/~mhisani/vdsl/2014-07-17/ConnectionStats-2014-07-17-09.47.35.txt

Please help!

Can you try the above mentioned program in order to monitor the errors on your line ? You should be able to tell as and when the errors start to increase dramatically which in tirn, can make it easier to narrow down any problems.....

Connection drops and change of IP address

Hi guys,
I've been having trouble with my broadband for some time. There is no issue with the speed, but my connection often drops, and as you can imagine this can be very annoying whilst gaming! There's nothing more annoying than being disconnected from a game of fifa (especially when winning!).
These connection drops happen almost every time the phone rings, and at other times seem completely random. Sometimes the phone will ring and the internet will not disconnect but most of the time it will. I've contacted BT and they advised me to change the filters, which I did with no result. So I contacted them again and they have arranged for a new router to be sent out.
Also I have noticed that my IP address changes every time I am disconnected, which causes problems with games which recognize the device you are playing on (namely RS and Gwars 2). This means I have to go into my email to verify my login every time I get a disconnect :/
So is there anything that I might be doing wrong on my end? Is there any way I can fix this?

Thanks here's the info

SBOD and disk errors-- oh my!

A month ago, a few weeks after I upgraded from Snow Leopard to Mountain Lion on my ~2010 21.5" Intel iMac, performance started to deteriorate, and the spinning beachball of death (SBOD) began to appear. (I do think the upgrade is a red herring.)
Safari seemed to trigger it most, though it happened at other times. So I disabled extensions and plugins, etc-- no dice. Then I looked at the console and saw that Kernel: disk0s2 I/O errors often happened when the SBOD appeared.
Questions:
1) I am hoping this is a hard drive problem based on the details below, labeled WHY I THINK DRIVE PROBLEM-- what do you all think?
2) When I wiped my disk (details below) I neglected to save the recovery partition. How do I get this back?
3) For some reason, I cannot boot off of my original snow leopard installation disc-- it always hangs after showing the bootup apple on the gray screen.
4) I also cannot use the "D" key on bootup to hardware test the system.
How can I get my recovery partition back? How can I test my system? Do you think the hard drive will have auto-mapped bad blocks, or do you think an imminent crash will occur?
DETAILS:
Disk Utility showed S.M.A.R.T. Verified, and said "No Apparent" problems with the hard drive (partitions) or volume-- though I am beginning to think that it would say a concrete slab had no apparent problems. I got SuperDuper (yes, I waited until I had problems! ) and tried making a current full backup to my time machine disk with SuperDuper, but it hung.
I tried resetting the NPROM and SMC, and around this time the iMac stopped booting-- it would hang with the spinning lines under the Apple on the gray screen forever. This happened regardless of pressing Command-R, or trying to go into Safe Mode. At these times, the top left of the iMac, above the slit, would get very hot. No fan would run.
I tried a number of things. Maybe the option key would have always worked, or maybe I had initially used the wrong key combination for NPROM, or hadn't waited long enough before restarting for the SMC. In any case, eventually I was able to boot again.
WHY I THINK DRIVE PROBLEM:
This time, I got a USB drive (Seagate Backup Plus) and used SuperDuper to back up to it. There were several places where I had to delete files to continue. It always stopped at the same file until I deleted it. On a large file, I attempted to use "Curl -C - -O file://<pathname>" to copy, but it never could copy past a certain point in the file.
This makes me think the problem is indeed a disk error, as opposed to a cable, controller, or software-- unless the controller is hiccupping with a certain bit combination of drive address, which I guess is possible.
I WIPED MY DISK: Anyway, I got the drive backed up with some original corrupted files deleted. Then I used Disk Utility to wipe the original disk, and did one pass zeroing it out. Then I restored the drive.
The result is a wonderfully responding iMac again... but I'm waiting for the other shoe to drop.

The boot drive is failing, or you have some other hardware fault.
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.

Connection drops and other problems

I've given up with getting any sense from the Indian call centres so hoping for some enlightenment here!
I've had the unlimited total broadband package since April 2010 and have had trouble-free usage right up to about a month ago. Now the service is just awful and I'm getting the following problems:
Broadband connection drops sporadically. Some days it'll be fine and stable, but others it's flakey - for instance it's dropped 3 times today already. Sometimes I'll get an orange light on the BT hub, but at other times it's showing all blue, although the connection has gone. Sometimes resetting the hub fixes it for awhile and sometimes it doesn't and connection comes back all on its own. Today I've had to reset the hub twice already!
At times I'll have a connection, but only to certain types of traffic. For instance I find that I can quite often do peer-to-peer stuff such as instant message, but all web browsing times out.
Speeds bounce around all over the place. I'm in a rural area so speeds have never been stellar, but at times it'll suddenly start crawling and can take 10-15 seconds to load a simple page like google.co.uk
The biggest issue I have is that my local exchange has BT wholesale as the sole provider, so even if I move ISPs it'll still be the same service, but I'll just have a middle man to deal with. It's particularly frustrating as I work from home and my office is hundreds of miles away so I absolutely rely on a good broadband connection for my living!
Does anyone have any ideas on what these issues could be? Much thanks in advance.

Home Hub: http://192.168.1.254/index.cgi?active_page=9116 << it only works if you have a Home Hub 2.0+ and remember to type your password in!

WRT54GL Connection drops and freezes

Hi,
I just recently purchased WRT54GL and I've been having an issue with it. Whenever I'm downloading (both regular download and progress download on you tube for e.g.), and I'm not browsing or active with internet explorer, it drops the connection, even worse, it freezes (idle) for sometime and back in a very low speed. Sometimes it doesn't come back up until I open an IE. It causes the downloads to fail every single time! I opened the Local Area Connection and i guessed it right, it does drop and stop so very often.
I tricked it with going "forward" and "back" on my IE to browse between two websites just to keep the connection "alive" so that the download doesn't get disconnected. I checked connecting my modem directly to the computer without the router and it worked great.
I have Comcast and Vonage connection.
if someone could help, I would very much appreciate it.
Thanks all, :-)

Your router needs to be Upgraded, Download the Firmware from here ,
Follow these steps to upgrade the firmware on the device: -
Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
Leave the username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...Check if this works for you...

Bootcamp: hal.dll and disk error SOLVED. Simple workaround

Many people had the "hal.dll missing" and "No disk" error while trying to install Windows with bootcamp on OSX leopard. I read a lot of workarounds and solutions, which some are complicated and some just don't work.
Here is my simple workaround to get rid of errors:
(Principle: force the shell of windows to appear before installation, so that we can quick format the bootcamp partition with" format" command)
1. Create a windows partition with bootcamp as usual (if you have already one then restore the OSX partition)
2. Restart and boot on windows cd. (press the option key ("alt") during restart)
3. When bluescreen appears and drivers are loading, press repeatedly F6 and F10. You should get a message that no SCSI disk was found and that you should press "S" or "enter" to continue. Press "enter". Now you should get a black screen in console mode.
4. Now we format the bootcamp partition. Type this: "FORMAT C: /Q /FS:NTFS". Put FAT32 instead of NTFS if you want the file system to be FAT32.
5. Press 'Y' to confirm.
6. Restart the computer, boot on cd, and install windows as usual. When arrived on partitionning during install, DO NOT REFORMAT!!!! Install on the partition that we just created before!
PS: I think that bootcamp just messes up the windows partition. That's why you get "disk error". When formatting during the windows installation, the partition is correct for windows but it overwrites entirely the bootcamp partition instead of just formatting it. I think that the quick format from the shell does just change the file system without modifying the partition itself. However, it works, so why bother why it does?....
Let me know if you have difficulties.

Perhaps you need to use an XP cd with sp2 slipstreamed, install boot camp update 2.1, then SP3.
The following URL has a note: --> http://support.apple.com/downloads/BootCamp_Update_2_1_for_WindowsXP
Important: Installation of Boot Camp 2.1 is required before installing Windows XP Service Pack 3 (SP3)

Oracle Application server connection pool and database links

I am using Oracle application server 10g with connection pools, the db used by the application connects to another oracle db using a database link. My question is when the application starts it creates 10 connections, does it also create x amount of database links as well?

Hi,
Is there any way to use the connection pool or Datasource while connecting to database?If I am using a stateless sesssion bean and using a Data Access layer which just creates a database session to write the persistence toplink objects how I can make use of application server connection pool?Hi Vinod,
Yes, TopLink allows you to use the app server's connection pooling and transaction services. Chapter 2 of the Oracle9iAS TopLink Foundation Library Guide provides details as do the TopLink examples. The easiest way to set this up is by using the sessions.xml file. The sample XML below is from the file <toplink903>\examples\ias\examples\ejb\sessionbean\sessions.xml. Here we are adding the datasource defined in OC4J and specifying that we are using the OC4J transaction controller also.
<login>
<user-name>sa</user-name>
<password></password>
<datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
<uses-external-transaction-controller>true</uses-external-transaction-controller>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<external-transaction-controller-class>oracle.toplink.jts.oracle9i.Oracle9iJTSExternalTransactionController</external-transaction-controller-class>
When using this approach you need to change your TopLink code slightly in the EJB methods:
a. Acquire the ACTIVE unit of work from the server
session (again, see the EmployeeSessionEJB code
example) with something like:
UnitOfWork uow = clientSession.getActiveUnitOfWork();
b. Calls to uow.commit() can be ommitted or commented out
because the EJB will handle this. Note that of course
the methods you create in the EJB that are using this
approach must have TX Required (default).
Hope this helps.

RE1000 Connection dropped and SSID visible

Hi to all, I've two big problem with the extender in object, the first one is the wifi connection dropped, tested with 2 mac and 2 iphone, this is very boring because every 2-3 the devices are offline. The second problem is that I can't hide the SSID while with my router I can. What should I do?
Some specs.
Router: Linksys/Cisco X2000
wifi: mode = mixed
channel amp = Auto (20 o 40 MHz)
channel = standard
SSID tranmission = hide
protection mode = WPA2 Personal
firmware v = 2.0.01
Extender: RE1000
Automatic configuration DHCP
Wifi = manual
firmware v = 1.0.02

To resolve intermittent wireless connection, you need to perform the following:
i. Reducing Wireless Interference
ii. Customizing Wireless Settings of the ADSL Gateway
iii. Checking the Placement of the ADSL gateway
Here is the link for solving the problem if the connection is dropping: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=95fb621ead264dda8c438f655f710630_4261.xml&pid=80&r...
Second, there is no such feature in RE1000 which can disable the broadcast of the SSID.

Actiontec Mi424WR Rev. I versus Rev. D -- range and connection drops and speed

Hello. I'm trying to figure out why the Rev. I is so much worse than the Rev. D for range and maintaining persistent connections at 30'+ in my home (two-story, single family). I have two smart phones, one tablet and a Blu-ray player, all 802.11n capable. I used the Rev. D for a few years with not many Internet problems overall (wired or wireless). I recently I got two Rev. I routers -the first was replaced after malfunctioning and overheating- but they both exhibited the same range problem. The Rev. D can usually keep a connection to the far reaches of my home - an upstairs bathroom about 60' away (straight line) through four obstructions (walls and floor). In that bathroom the speed test was slow of course (~1.8 Mbps) but the connection persisted for several minutes without dropping and reconnecting to the router even once. But the Rev. I could not keep a consistent connection to the tablet in the kitchen at only 40' away through only 2 walls (around two bends). So I had to move the tablet a little closer within the kitchen - 30' away to stream video consistently well. On my cell phone at 30' away I had to turn off the auto network switch to 4G just to keep a persistent connection to the Rev. I. With the Rev. D I never had any dropped connection anywhere in the kitchen on the tablet or the phones. Here's what I've learned so far in my own tests and reading other people's experiences here and elsewhere on the web. Any additional insight would be helpful. -- I have read that the signal strength of the Rev. I was reduced for security concerns. I can verify with a Wi-Fi scanner app on my phone that the signal strength is about 2-3dB less (about half as strong) for the Rev. I starting at about 25' away. That shouldn't necessarily cause the connection to the Rev. I router to drop and reconnect so often after 40' of distance. Any ideas why the connection drops so easily and often? The signal strength at 0 distance (the antenna touching the phone) was about identical for both revisions. -- I have read that the Rev. I wireless mode should be in either performance (n only) or mixed (b/g/n) to maintain better connections but either setting made little difference. I have always kept the Rev. D router in mixed mode (b/g). From the antenna signal strength test above, I discovered only one antenna on the Rev. I router sends a signal so I doesn't seem like there is any beamforming being done in performance (n only) mode which is disappointing. Any idea why beamforming is not enabled? Is the second antenna even used on the Rev. I? -- I have read that the antennas are too small on the Rev. I and a bigger antenna will help. That part I know is false especially if the longer antenna's impedance doesn't match the router's antenna port. The "ideal" antenna length at 2.4GHz is about 2.5 inches and the Rev. I antenna looks that long. It seems inside the Rev. D antenna is a cable or some waveguide (the thicker, bottom 5" of the antenna) which might help reduce interference by moving the actual antenna portion of the Rev. D away from the router housing, the power cable and the data cables. -- Sitting 10 feet away from the router, I didn't notice any difference on speed tests. It was topping out at about 15-18Mbps for either router revision. So the whole point of having an 802.11n router for faster speed is moot. And at greater distances (40'+) I can't get a reliable connection so the Rev. D wins by default. If anyone has any ideas to make the Rev. I better I would like to try them. Verizon didn't want the Rev. D router back so I have both revisions to use. Thanks!

I finally got the Quantum Gateway router (FiOS-G1100 rev 1.03 firmware 0.17.52) and it works great on both 2.4GHz and 5GHz. In most areas of my home and on both bands I tested about 42 Mbps up/down using the Ookla speedtest app (my internet speed is 50/50 Mbps and I test about 58 Mbps using a wired connection). Previously with the Rev. D I was getting about 18 Mbps up/down in most areas of my home. In the farthest place in my home from the router (an upstairs bathroom) I get 22 Mbps up and 42 down which is impressive considering I was only getting 2Mbps with the Rev. D. The Quantum router has a similar signal strength profile as the old Rev D - about -18 dBm right near the router and about -70dBm to -80 dBm in the bathroom furthest from the router (55 feet straight line that goes up one floor and through three walls). I used the Wifi Analyzer app to see the signal strength. Not many of my neighbors have 5 GHz routers so there are still lots of free channels up there. I also noticed the Quantum router has a power setting so the power can be turned down if someone is in an apartment or condo. But for me the lots in my neighborhood are 1/2 acre so I'll leave the power setting at 100%. I like having good speed in the far reaches of my home without using a repeater or extender.

Connection drops and then very slow speeds.

I don't know what's caused this. My broadband has been stable at 7Mb/s downstream for about 6 months now. But a few days ago my connection kept dropping randomly. Now it's stabilised but my speed is way down.

I've done all the usual things with wiring everything up, changing filters and using the connection behind the faceplate. I've tried to run the test at speedtester.bt.com but I just get an error whenever I try. When I run the test at speedtest.net I get-
Ping: 44ms
Download 1.22Mbps
Upload 0.37Mbps
which is quite a bit slower than what the router says, but it feels even slower than that.
I'm not sure if this just needs a reset at the other end because of all the disconnections or if I've got a real problem but an help would be appriciated.

I finally got speedtester to work. I says the maximum my line can handle is 2000kbps but I used to get 7000. Does this look like a problem with the line?
