------------------------------------

[~vinodkv], I suspect its a single user for everything. [~gu chi] can  confirm though.

> Suppose one container finished, then it will do clean up, the PID file still exist and
will trigger once singalContainer, this will kill the process with the pid in PID file, but
as container already finished, so this PID may be occupied by other process, this may cause
serious issue.
> As I know, my NM was killed unexpectedly, what I described can be the cause. Even rarely
occur.
