I'm running nagios 3.2.0 with NDO 1.4b7. I mixed active and passive checks and it receives events from another nagios instance (50 hosts for 500 services). Since last week, I see nagios stops to perform active checks : the 'last check' is in the past and the 'next scheduled check' too. The only way to recover the situation and allow nagios to perform active checks is to restart nagios. But after hours, the problem occurs again.
Currently I put a cron job to restart every 4 hours nagios but it couldn't be a final solution.
Some of you already faced this problem and fixed it ? I'm running mutiple nagios instances and I see this pb only with that one.
Thanks in advance for any inputs.
