Re: "Execution Failed"

[Martin Pala]

Hi,

the execution error flag is set, because monit wasn't able to start the process 
… the root cause could be, that either the stat program failed to start it - 
for example because of some missing environment variable: monit executes the 
programs in the sandbox and purges environment variables, it sets just basic 
PATH=/bin:/usr/bin:/sbin:/usr/sbin. Another possible reason could be, that the 
service start was too slow (based on the output your start timeout 30s, which 
is the default).

If somebody starts the service manually (out of monit control), the execution 
error flag remains set as a reminder, that monit wasn't able to start it => the 
configuration should be fixed.

To clear the flag, just unmonitor and monitor the service:

    monit unmonitor pixelServer
    monit monitor pixelServer

Regards,
Martin
