Asterisk 1.6 segfaulting

Hi. We’re running Asterisk 1.6 on a very beefy server running Linux kernel 2.6.28. Asterisk itself is segfaulting fairly regularly. It seems to happen under what for us is a heavy load- 12-16 simultaneous calls. The script that runs Asterisk automatically restarts it after this, and sometimes it’ll segfault almost immediately after restart. However, sometimes it’ll run for days without problems. I have upgraded to Asterisk and it’s still happening. Nothing gets logged other than the syslog crash event, which I have pasted below. Running GCC 4.3.3 (though it was crashing before this version), and glibc 2.9. Any ideas?

asterisk[30477]: segfault at 10 ip 00007f9b644e04ea sp 00007f9b50171330 error 4 in[7f9b644d8000+16000]
asterisk[30562]: segfault at 10 ip 00007f28b84ce4ea sp 00007f28a0380650 error 4 in[7f28b84c6000+16000]

So is mine. I’m running 1.6.1-beta4.
It seg faults on an IAX call to 1.2 boxes and 1.6.1-beta4 boxes.

I haven’t tried 1.4, but I think it’s pretty irrelevant.
Here is the thread - no responses so far.

My seg faulting has stopped with 1.6.1-rc1 which was released yesterday.
