Summary:                    Asterisk forks processes then locks up
Description: 
One particular Asterisk 1.4.21.1 machine occasionally forks off some child
processes, goes to 100% CPU, and stops responding to calls and the console,
and stops logging. During this time:

test:~# ps -ef | grep asterisk | grep -v grep
root      4830     1  0 Sep07 ?        00:00:00 /bin/sh
/usr/sbin/safe_asterisk -U enswitch -G enswitch
enswitch 25822  4830 55 Sep29 ?        1-16:05:51 /usr/sbin/asterisk -U
enswitch -G enswitch -vvvg -c
enswitch 16080 25822  0 09:33 ?        00:00:00 [asterisk] <defunct>
enswitch 27846 25822  0 14:59 ?        00:00:00 [asterisk] <defunct>
enswitch 12656 25822 99 17:09 ?        00:19:04 /usr/sbin/asterisk -U
enswitch -G enswitch -vvvg -c

The "top" command shows that both process 25822 and 12656 are using 100%
CPU time.

Killing the processes and having safe_asterisk restart Asterisk fixes the
problem in the short term.

Any ideas on how to debug this?
