What Do I Expect To Happen?
I expect system to no drop network packets

What Happened Instead?
As you can see, server is dropping quite a few network packets.

Please let me know if you need any additional information.

NOTE: As a test, I installed 3 other machines (2 HP Server Class (DL380 and DL580) and One Laptop (Asus)) with similar installed software, but not from upgrade; fresh installed. All machines had same problem on br0 interface.

Thanks, Brad, for confirming the bug...

Is there any more information you need from my system, or, are you ok to start working on it? Have you been able to reproduce?

Thanks!

Just thought I would chime in and letting you know that this is also affecting me. Wireless seems fine but wired packets are dropping inbound. I don't loose link and wireshark is still sending ping to the gateway ip with no response when this happens. It is inconsistent for me but when running a long ping I'm getting anywhere from 2% to 10% packet loss.

Joeman1, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi Chris,

Yes, well, this issue was reported a year ago and there has been no interest from Canonical on releasing a fix or even acknowledging that there was an issue at all despite other having the same problem and even reporting it here.

Until Canonical understands the needs of the enterprise community and started paying attention to issues that come up, its going to be a long time before they are a billion dollar company or even close to it.

That said, we have moved our infrastructure to RHEL where we get much snappier support; even from the community members.

Sorry it didn't work out; however, we still have a few desktops running Kubuntu, but seems like even that version doesn't mean too much to Canonical these days... Pitty...

You can close out this ticket - unless the others that reported the issue have moved on too. Might want to do your best to keep what existing customers you have left.

Good day!

Joe

Still exists with 12.04.

Or 10.04 and backport kernel.

I am not understanding the process here. This was submitted as a bug, has not been fixed, but was closed. I am evaluating Ubuntu to use as a sniffer, but if I am understanding this process correctly, things don't get fixed in this distro. Am I wrong? Was this fixed somewhere and I don't see it? My implementation is also dropping packets. As it is, this is not useful.

This problem still persists as of quantal 12.10 with the symptom of slow packet loss.

Suggest someone update this ticket with specific instructions about how to...

1) determine the protocol where packets are dropping

2) isolate the process where packets are dropping

ifconfig simply shows dropped RX packets for the adapter. More specifics are required to
determine the packet drop source.

Thanks.
