Re: monit5.5: Problem with process restart

[Martin Pala]

Monit executes the program using execv() ... it doesn't interpret it as script. You need to specify the interpreter at the script start, for example:

--8<--

#!/bin/bash

...

--8<--

Thanks Martin.

With verbose mode, I was able to see that monit was complaining about missing "stop program" in the config file.

Got around the error and added a new script to handle start/stop of the process. Still, its failing to restart.

Here is corresponding log entry:

Script:

exit $?
