Re: Monit running start program multiple times

[Martin Pala]

Hi,

the start program waits for the program to start (show up in the process 
table). If the pidfile based monitoring is used, it depends on the pidfile 
content => if pidfile is not updated, Monit won't find the process.

Some process management frameworks (such as Upstart on RHEL 6.x) have problems 
if stop is called and before it finished (even when process is stopped 
already), start is called - then the pidfile is not created/updated. In such 
case it's better to add standalone "restart program" to Monit configuration 
(supported since Monit 5.7), which does atomic restart (from Monit point of 
view) instead of stop+start.

Regards,
Martin
