we’ve been running nagios for a few weeks without any major
hassles, but in the last 5 hours it got its knickers in a twist twice.
When the server it is running on had a pretty high load for a few
minutes it fired alerts that pings timed out or the smtp agent
couldn’t run in a given time … however, those notifications
didn’t go away after the load went back to normal (they stay
for hours if I let them). The only way to get the status display
clean again is to stop and start nagios (which isn’t really that
great a solution). Is that behaviour normal? Am I just expecting
to much? Or is there a configuration key I need to modify
to have it tidy up itself?
