Re: monit doesn't see pid file

[Paul Theodoropoulos]

Does the content of /var/run/stream.pid match the running process ID?


I'll ask the obvious - have you done a 'monit reload'? I've run into 
circumstances when initiating monitoring of a new service where things 
can get somewhat 'out of sync', and one or two 'monit reload's are 
necessary to get it working properly.
