Summary:                    high SIP call volume locks Asterisk 1.4.19rc3
Description: 
I am able to reliably lock up Asterisk and send the loadavg on the server
to 100.00 and higher within 5 minutes of starting performance testing with
300+ channels(all SIP). With IAX, even at higher call volumes, it does not
crash at all.

Here is a link to the 20,000+ line GDB output:

I tried doing a "core show threads" but Asterisk was not responding.

I hope that you got decent error messages. We do complain when we can't
open more file handles.

SIP channels die more slowly, since we have to have them hanging around
for a while to handle re-transmits. That's not needed for IAX2.
