Summary: [patch] chan_sip random deadlock
Description:
I have asterisk installed on a 64-bit debian 5.0, with realtime config for
sip peers.
Asterisk randomly stops processing SIP calls. I cannot find a pattern of
external events triggering it.
When this happens chan_sip appears totally frozen and even established
calls stop routing RTP.
I have compiled asterisk with all debuging input enabled. When this
happers 'core show locks' presents this:
