Hi Jason. Thanks for looking into it. Here is a log and the output of "bt full" : http://pastebin.com/PdXiZSV8 . Scenario : A call comes in, then the first INVITE is relayed somewhere, and there is no reply coming to it (there are retransmissions) , kamailio is generating a 503 , and then the negative ACK comes, and then it crashes.
