Dovid,

The number of concurrent calls on the server is tightly related to the 
number of file handles Asterisk opens, so that's the first place that I 
would look.

Take a look at 'ls -l /proc/`cat /var/run/asterisk.pid`/fd/' if you 
really want to analyze the file handles Asterisk has open.  Doing this 
on a server that has experienced the problem and one that hasn't might 
be revealing.

You could also try running 'lsof | egrep "^asterisk "' periodically on 
one of the affected servers and capturing the output to timestamped 
files.  Comparing the data in the files leading up to a "Too many open 
files" error should be revealing.
