Dov,

I agree with the first response.  Your system is failing at an abnormal 
rate.  Please share more information about your setup so that we can 
help you.  Hardware, software, OS, configuration...there's no such thing 
as too many details when trying to work out these problems via a mailing 
list.

Information about what tasks you are asking Asterisk to perform and how 
you have it configured to do so is vital.  In particular, I'm curious to 
know if you're recording the calls using the Monitor() application?  53 
concurrent calls being recorded directly to disk is about where things 
start to go south (it's an I/O bottleneck, not CPU).  If you have a 
Digium card in the box, make sure that it's not sharing an interrupt 
with any other hardware.  The list and the wiki both have plenty of 
information to help you with that.
