Attachment: valgrind.txt
I ran Asterisk in Valgrind until Asterisk CLI started spitting out stuff like:
[2014-08-03 11:39:37] ERROR[30855]: chan_iax2.c:2556 peercnt_add: maxcallnumber limit of 2048 for 192.168.192.196 has been reached!

valgrind.txt attached.
I am running another trace with verbose+debug+iax2 set debug on and will supply gdb and core show locks output once * locks again.
All output is with the patch on v11 subversion.

> I have regularly (once a week, once per few hundred calls?) been having
> problems with Asterisk's SIP stack not responding to packets from any of
> my registered devices. In the past, I could not tolerate the outage, so
> i would restart asterisk to make things happy.
> My Asterisk server is currently in this broken state and I can leave it
> this way for a short while. Devices are registered to it and I can 'sip
> qualify peer xxx' - see [^qualify.txt]. notice the console/debug does not show the return packet, but on the network, the device has clearly replied - [^qualify-tcpdump.txt]
> 'sip show peer xxx' all show Status OK [^sip-show-peer.txt]
> but whenever one of the devices tries to make a new call, Asterisk just
> doesnt respond. 'sip set debug on' shows no packets.
> from the asterisk server (10.1.0.3), i can see one of my phones
> (10.1.0.111) trying to make a call but Asterisk won't talk back.
