The utility that runs when a process is killed is cgroup-reap-all, which ensures that all the PIDs from the cgroup are killed. It does this by killing them, but also ensuring that the list becomes empty. It can do multiple requests to ensure that the application isn't avoiding being killed by trying to "out spawn" the cleanup utility. http://bazaar.launchpad.net/~indicator-applet-developers/ubuntu-app- launch/trunk.rtm-14.09/view/head:/cgroup-reap-all.c It could be triggering a race in cgproxy where a PID is leaving the group, or the group is being destroyed at the same time as the reaper is asking for the PIDs in it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394919 Title: cgproxy hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1394919/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Here are all the logs you requested. The first dbus-send command hangs and the second works.

i am pretty sure this is simply the same as bug 1377332 the core issue with cgmanager from this bug was never fixed (it is in critical, incomplete and unassigned state) only workarounds have been put in place to hide the symptoms in ubuntu-app-launch. the actual crash/breakage was never fixed. according to commant #38 in the above bug i enabled the debug mode for cgmanager now. i belive everyone who could repro this bug should try to do the same to collect as much info as we can. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394919 Title: constant crash in trying to collect info for recoverable error of cgmanager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1394919/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We landed in Vivid on Friday the fix for the flickering windows and not reporting the recoverable error. While neither directly relates, this could possibly be after effects of those.
