That should have been /proc/[0-9]*/task/* (not "tasks") Pull request: https://github.com/openshift/origin-server/pull/3910 Here's how to verify for Q/E... 1. Create a non-scaled jbosseap app and note the gear uuid - both spawn a ton of threads 2. Find out how many threads are in the gear cgroup, should be over 60. wc -l /cgroup/all/openshift/[UUID]/tasks 3. Move the tasks to the root cgroup cat /cgroup/all/openshift/[UUID]/tasks | while read t; echo $t > /cgroup/all/tasks; done 4. This should now be 0, no threads in the gear cgroup wc -l /cgroup/all/openshift/[UUID]/tasks 5. Repair the cgroup oo-cgroup-reclassify -c [UUID] 6. This should now be the number from #2 (or very close) wc -l /cgroup/all/openshift/[UUID]/tasks Commit pushed to master at https://github.com/openshift/origin-server https://github.com/openshift/origin-server/commit/b65344195881663880fb52302b7060cd67ccd3e5 Bug 1020029 - needed to enumerate all threads in the task dir.

Move to verified. Moving back to VERIFIED, since this wasn't actually in yesterday's release. |
