Zenoss 4.2.3 CentOS 5.4
In the last week the zenoss services (daemons) are crashing every hour (exactly, every hour! x:00), each time for 2-3 minutes.
I didn't change anything in zenoss settings, due to those crashes all our graphs are incomplete and fragmented.
I checked each daemon logs but couldn't find any indication for errors.
This daemons / processes crashing:
zenprocess, zenjmx, zenperfsnmp, zeneventlog, zenmodeler, zencommand, zenwinperf, zeneventd, zenhub, zenactiond, zenwin, zentrap, zenstatus, zensyslog, zenping
This is very critical for us, and I would really appreciate any troubleshooting suggests,
Is there any additional logs to check? specific log to enable debug?
