One of the LXC running on ProxMox is unable to shutdown or stop. When I attempt to runi 'ps aux' to see what the PID is to kill the process it is unable to run.
When I run

So there is a zombie process? Could this be preventing me from stopping the LXC?
When I run
strace ps aux I get the following:
