Pieter De Wit, 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? If so, could you please test for this with the latest development release of Ubuntu server? ISO images are available from http://cdimage.ubuntu.com/ubuntu-server/daily/current/ .
If it remains an issue, please just make a comment to this. If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc6 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1055192 Title: After 1000's of small connections traffic on those connections stop Status in “linux” package in Ubuntu: Incomplete Bug description: Hi, I have two VM's setup with e1000 drivers. I use iperf in server mode on the one and in client mode on the other. On the client I run the following in a while "true" loop: iperf -c <server_ip> -P 8 -i 5 -l 1k I run about 50 of those in background. After about 40 seconds traffic just stops. new connections are still made and working, but these all stop. Something like ping never stops and I can ssh to the box and all other connections are maintained. I do see a message in the kernel about SYN cookies being sent, but disabling this doesn't solve the problem. Switching the network to vmnet3 solves the problem, but this has a bunch of issues itself.
