I run Nagios in a dual-CPU VM (CentOS 5.2 guest on VMWare ESX 
3.something).  Once in a while, Nagios would shut down some time after 
midnight.  I suspect that ESX is pretty busy while the other VMs are 
being backed up.  The system log had entries like this:

Jan  7 00:18:17 Monitor2 nagios: Caught SIGSEGV, shutting down...
Jan  7 00:18:27 Monitor2 kernel: BUG: soft lockup - CPU#1 stuck for 10s! 
[check_nt:21036] Jan  7 00:18:27 Monitor2 kernel: CPU 1:

It didn't happen all the time, and there wasn't much I could do about it 
when it did happen.  I created another Nagios VM identical to the first, 
except it's got a script which monitors the primary server and takes 
over if the primary fails.  Nagios is not started on the failover 
server, so it takes very few resources to keep idling along.

There are ~550 hosts and ~4500 services being monitored, and the two 
virtual CPUs run around 80% each in the Gnome system monitor app, and 
1.3-2.0 in the load averages.  They're both 3.0 virtual GHz, if I recall 
correctly.  I have large installation tweaks turned on as well.  The 
Nagios server is busy enough all the time that the server guys have 
mentioned going back to physical hardware if I have to add much more.

 From a user's perspective, I can't tell it's on a VM.  I think the 
slowest part is how quickly my PC can render Nagios' web pages.
