Customer can not stop or restart the container. Restart of the node helps for while, then issue is come back:
[root@myhost ]# vzctl restart 111 Stopping the Container ... Set up iolimit: 0 Set up iopslimit: 0 Unable to stop the Container; operation timed out
Some software inside the container created zombie processes, so
vzctl stop cannot kill them even with
--fast key - some processes are left in
Z state. Since there are some processed inside the container - it cannot be stopped.
Reboot the server to release the container and uninstall or fix the faulty software inside the container.
