[Bug 284229] Re: console-kit-daemon using a lot of cpu
** Description changed: + The use of pam-ck-connector means that consolekit registers a session for every cron or ssh session + started. Registering a session involves creating a dbus proxy. Internally to glib these are stored in a list, + and only removed when unref'd, but the code fails to do that. If many sessions are opened + (high frequency cron for instance) then the list grows in length, and operations that traverse the list take + increasing amounts of time. This can lead to consolekit taking up large amounts of CPU time. + + The fix is simply to unref the dbus proxy when we are removing the session. It is then removed from the + internal list and causes no problems. This fix was deployed in jaunty on 2009/01/27. + + The patch for Intrepid is available in a later comment. + + TEST CASE: + 1. With an ssh server installed on the machine and keys set up so you can log in without password run + do while `true`; do ssh localhost echo '$$'; done + and leave it running overnight. It should lead to console-kit-daemon using a high percentage of the CPU. + + The regression potential should be low as unrefing something that is no longer used when the session + is being removed should not be a problem. + + === Original Report === + Binary package hint: consolekit Since the last reboot, a strange and to me unknown process, console-kit- dae, has been using up more and more cpu.

Running `pam-auth-update` allows you to remove using ConsoleKit as a session manager. I then killed off console-kit-daemon and it has not restarted since (lots of remote cron tasks). Use of ConsoleKit on a box that gets connected to at a minimum of once a minute over a 2 month period has lead to a process that slows down ssh login to take over 30 seconds, which in turn creates problems.

[Bug 284229] Re: console-kit-daemon using a lot of cpu
hi, on my system (8.10 desktop) i installed a x2go and this server opens every 5 secons a new session (as my posting above shows). and as the pam_ck_connector is installed to (/etc/pam.d/common-session), this session is registered with the consolekit-daemon -- every 5 seconds a new session is registered with consolekit-daemon. i don't know if this session is deregistered. i only see, that if i disable this session inflation, consolekit-daemon also is ok. perhaps some of you have another daemon running which also opens a lot of sessions in the background. so don't look if you have a x2go, look for something which creates very much sessions. this was my main problem. perhaps it helps to disable pam_ck_connector? i don't know if this is needed ... only my 2 cents ... -- console-kit-daemon using a lot of cpu https://bugs.launchpad.net/bugs/284229 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Ulrich, I have had a look at my auth file and don't see any mention of x2goserver yet still see the consolekit problem however with less frequency than I used to. I think you might have a seperate issue that inflames the consolekit bug. Sorry, about to go off topic but a little interesting all the same: I would have thought that all you guys running a server would be using the 8.04 LTS edition which doesn't have this problem and is more intended for long term deployment (On the desktop this issue is a mere hindrance). That said I would have though the Ubuntu web servers would have been on 8.04 and not Dapper 6.04 as looking at Netcraft: http://toolbar.netcraft.com/site_report?url=http://www.ubuntu.com it reports the version in use is Apache/2.0.55 which is the version used in Dapper 6.04: http://packages.ubuntu.com/dapper/web/apache2 Like I said off topic but interesting none the less. -- console-kit-daemon using a lot of cpu https://bugs.launchpad.net/bugs/284229 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think you would be able to reproduce it with just slightly more testing time. 1000 logins probably isn't enough to reveal the problem.

Similarly, I have a headless server that does all its work from cron. After a while (maybe a week), it's unusable because console-kit-daemon is taking 99% of the CPU.

[Bug 284229] Re: console-kit-daemon using a lot of cpu
Hi, I have tried the ssh loop to try and trigger this, and console-kit-daemon uses a few percent CPU while it is running, but then immediately falls back to zero when it is killed. Do I need to wait longer for this to become evident? I am up to session 1096.

[Bug 284229] Re: console-kit-daemon using a lot of cpu
The way I read it, sessions are being leaked into console-kit-daemon, and every time a session is added or removed console-kit-daemon does something that's either O(N) or O(N^2) or worse. I'm up to Session #31399 and every time a session is added or removed, c-k-d eats another 4 or 5 CPU seconds (100% utilization for several seconds). This would also account for c-k-d's ever-increasing memory size. From what I can tell, the extra sessions are due to cron. I have some cron jobs that fire every minute, so they are creating and destroying sessions pretty frequently. Which means that I'm leaking a session every minute. The superlinear big-O explains why c-k-d is taking an increasingly large fraction of CPU time as the system stays up longer. It was 4.1% yesterday and it's up to 4.8% now. It takes me 2-3 seconds to sudo because c-k-d is spending so long with its head up its ass. I suspect that this would hit anyone with minutely cron jobs. ** Attachment added: output of dbus-monitor --system over 5 minutes. http://launchpadlibrarian.net/19148986/dbus.out -- console-kit-daemon using a lot of cpu https://bugs.launchpad.net/bugs/284229 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 284229] Re: console-kit-daemon using a lot of cpu
Here's a really easy way to reproduce this problem. Assuming you have an ssh keypair which allows you to login on your own machine, do this: while `true`; do ssh localhost exit; done; console-kit-daemon will runaway with the CPU eventually. In my opinion this is a very serious problem for anybody running Ubuntu who has a lot of users or who has cron jobs. -- console-kit-daemon using a lot of cpu https://bugs.launchpad.net/bugs/284229 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, Thanks, you have some dbus activity, and it appears to be opening and closing sessions. Could you also grab some output from dbus-monitor --system so that we can watch the traffic (you might want to screen the output to check for private information) Also your /var/log/ConsoleKit/history file would be useful.
