Summary:                    [patch] 1.6.0.1 crashes randomly
Description: 
Hi, 

 I've compiled 1.6.0.1 on my box on Monday and since then I had few totaly
random coredumps. Some of them were done durring night when no
call-processing is done, some of them durring peak-time.
 
 Asterisk @ IBM x3400 + Sangoma A104d (wanpipe 3.3.14) + DAHDI 2.0 +
asterisk-addons
Kernel 2.6.19-7
gcc 4.1.2

420 SIP peers, 55 IAX2 peers (IAX modems).

Please find attached gbd output, from this output I think that crash is
caused by iax2

On busy systems, it's possible for the values checked within a single line
of code to change, unless the structure is locked to ensure a consistent
state.
