I assume monit was trying to check the status of process 23953, but why would it fail?

Hi,
running 5.2.5-1, I have 3 services, openvpn_server, ntpd and named. ntpd and named are dependant on openvpn_server.
monit was told to restart openvpn_server, the log extract below appears to show that monit converted this into a stop and start which ran too close together.
I think that the stop had not completed when the start began, which is why the pid file was not present, the pid file was then removed by the stop,
This left openvpn_server in a state such that monit kept restarting it, but failed (see second extract), which kept repeating
