Thanks for the bug report. Did you notice any leak in 'struct pids' also or just the pid_namespace ? If the pids are not leaking, this may be slightly different from the problem Catalin Marinas ran into: http://lkml.org/lkml/2009/7/29/406 And the pid_namespace does not seem to reproduce for me, with out the 'ls -al /proc/...' above, or with the simpler 'ns_exec' approach to creating pid namespace. I am going through the code for lxc-execute, but does it remount /proc in the container ?
