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
