ok, I can replicate this easily, have the process (in my case openvpn_server) running, remove the pid file. Every time round the cycle monit tries to start openvpn_server as there is no pid file, but opnevpn immediately exits as it cannot get control of the port due to the original copy that is still running. repeat
