    Description

      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.
