Do you get any log entries in /usr/local/nagios/var/nagios.log about orphan checks?

Ok, you can do a quick grep on that file with the following command:

Code: Select all

grep orphan /usr/local/nagios/var/nagios.log

Hi,
This is what i found in nagios.log:

[1354905399] SERVICE ALERT: SRDCDPZATEBEO;PING;OK;SOFT;2;PING OK - Packet loss = 0%, RTA = 16.88 ms
[1354905459] Warning: The check of host 'orapru' looks like it was orphaned (results never came back). I'm scheduling an immediate check of the host...

Lets start with this and see if the issue persists from there:

Code: Select all

service nagios stop
killall -9 nagios
service nagios start
All times are UTC-05:00
