I'll PM the others to Scott...

Thanks!

You are most definitely short on memory. This nagios box only has 768MB of RAM . . .

Hi! I don't mind throwing more RAM at it, just want to make sure I'm not masking some other issue. This has been running for over a year, maybe 2. Never had these alerts before until upgrading to 2.2....

I would stick more ram in it first. The older your install gets, the more likely you will notice a slight increase in ram usage as your mysql tables grow in size.

Thanks! I'll give that a shot and also a reboot. Never did reboot after the upgrade... Couldn't hurt, right?

OK, 2GB now and fresh RAM... I'll keep my eye on it... Thanks!

You are most welcome, cheers!
