Have disable the Jitter Buffer on SIP and Zap channels and all look to work correctly, server up since 24 hours, about 2000 calls.

With jitterbuffer, it crashed 3-4 times daily.

Not sure if fully related, but on trace we see the following line, why we disabled JB :

0000008 0x0805703a in ast_jb_get_and_deliver ()

Just got same problem on another server today and have uploaded new back trace. Meantime, I've ask the customer to disable Jitterbuffer to see if it help.
