pmlogger service fails daily at 00:10 with error message "New main PID XXX does not belong to service, and PID file is not owned by root. Refusing."

Issue

• Daily, at 00:10, pmlogger.service unit fails and print the following messages:

  pmlogger: Starting pmlogger ...
  systemd: Can't open PID file /run/pcp/pmlogger.pid (yet?) after start: No such file or directory
  systemd: New main PID XXX does not belong to service, and PID file is not owned by root. Refusing.
  systemd: New main PID XXX does not belong to service, and PID file is not owned by root. Refusing.
  systemd: pmlogger.service never wrote its PID file. Failing.
  systemd: Failed to start Performance Metrics Archive Logger.
  systemd: Unit pmlogger.service entered failed state.
  systemd: pmlogger.service failed.
  

• Then pmlogger.service unit restarts automatically
