Subject: pidns memory leak
Date: Fri, 02 Oct 2009 14:27:04 +0200 [thread overview]
Message-ID: <4AC5F198.2070407@fr.ibm.com> (raw)
Hi,
I am facing a problem with the pid namespace when I launch the following
lxc commands:
lxc-execute -n foo sleep 3600 &
ls -al /proc/$(pidof lxc-init)/exe && lxc-stop -n foo
All the processes related to the container are killed, but there is
still a refcount on the pid_namespace which is never released.
That can be verified in /proc/slabinfo. Running a test suite with
thousand of tests quickly exhaust the memory and the oom killer is
triggered.
Reproduced with a 2.6.31 vanilla kernel on i686 and x86_64 architecture.
Thanks
-- Daniel
