Hello,
monit checks the service in intervals given by the "set daemon <x>" settings.
If the interval between checks is long or the check is blocked by some service
timeout/action, then the interval can be longer.
Please can you check the "set daemon" settings and run monit in debug mode?:
1.) stop monit
2.) monit -vI
Best regards,
Martin
