4.11 Server Locks Up

Over the past few months I have noticed that our mail server is flat out 
locking up.  I monitor it via Nagios and about once every two months I 
get emails saying it is down and when I go over to the console the 
server is totally unresponsive.  I've gone through logs every time and 
find nothing at all wrong. 

This is a Dell PowerEdge 2850 with Dual Xeon cpu's and 2GB of memory.

One, has anyone else had similar problems with boxes just becoming 
unresponsive under high load?  Two, is there any reason this would occur?
