[Bug 1462919] Re: kswapd pulls server down every 2 weeks.
I experience the same on desktop (15.04) maybe once a week. I presume that this happens when some laking application starts to eat up all the memory quickly. When this happens the whole machine gets unresponsive immediately and only restarting helps. It only turns out from the atop logs what happened after the machine was restarted. Atop is configured to run every 30 secs. It is visible from the atop logs that kswapd0 is eating up all the cpu resources. Strange thing is that this happens despite there is no swap enabled. I suppose what should happen is that the kernel OOMs and kills some application and everything is back to normal. What happens though is that the machine dies. Of course every unsaved work and open windows and applications are lost, which is very unfortunate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.

[Bug 1462919] Re: kswapd pulls server down every 2 weeks.
I'm very sure that it happens to every 15.04 system running continuously 24/7. BUT it seem to be very much related to the java-stuff involved in running Jenkins or a TeamCity agent (as with the actual affected system). I have not upgraded the BIOS yet - and I do not think that it could affect it. But I will upgrade it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.

[Bug 1462919] Re: kswapd pulls server down every 2 weeks.
On one of the machine suffering from this I run jenkins. Shutting down jenkins immediately gets kswapd back to normal. Starting jenkins again makes kswapd spin again. But a reboot mitigates the problem for several days.

Re: [Bug 1462919] Re: kswapd pulls server down every 2 weeks.
It happenend after upgrading to 15.04 For some reason the system still used kernel 3.13 after the upgrade - on which it failed. Upgrading to 3.19 did not change anything. I have difficulties believing that and userspace sutff could cause it, but maybe the systemd-stuff could affect it anyhow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.

[Bug 1462919] Re: kswapd pulls server down every 2 weeks.
Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.

[Bug 1462919] Re: kswapd pulls server down every 2 weeks.
Søren Holm, thank you for reporting this and helping make Ubuntu better. As per https://downloadcenter.intel.com/product/36456/Intel-Server- Board-S5520UR an update to your computer's buggy and outdated BIOS is available (64;64;26;1.12). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Changed in: linux (Ubuntu) Importance: Critical = High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.

[Bug 1462919] Re: kswapd pulls server down every 2 weeks.
Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get dist-upgrade If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging. Thank you for your help, we really do appreciate it. ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete ** Tags added: kernel-request-3.19.0-15.15 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462919 Title: kswapd pulls server down every 2 weeks.
