> pid files are deleting in 5 seconds after we stop the daemons. If a start command were
executed within the 5 seconds, the pid file will be overwrite with a new pid. However, this
pid file is going to be deleted by the former stop command. This is causing the monitoring
service to lose track of the daemons, hence keep rebooting them
