Hello I'm running PJSIP 2.6 on iOS and I've had this crash happening here and there for almost two years. I recently noticed an uptick of occurrences so I am trying to figure out what can I do about it. This crash occurs when receiving a BYE message and the client attempts to destroy the ICE stream transport. If this takes too long, we end up with a crash when calling pj_grp_lock_acquire(sess->grp_lock); in pj_turn_session_on_rx_pkt in turn_session.c:1154, I'm assuming because sess becomes NULL. In turn_sock.c:611 in on_data_read there's: while ((pkt_len=has_packet(turn_sock, data, size)) != 0) { ... pj_turn_session_on_rx_pkt(turn_sock->sess, data, size, &parsed_len); ... } But I guess turn_sock->sess can become NULL at any point during the iteration. Is there anything I can do (that won't throw off everything else) to make sure pj_turn_session_on_rx_pkt isn't called when the sess is already NULL? I'm thinking of just adding a check around it and keep the rest of the code as is, but I'm not sure if that won't mess up the while condition and crash within has_packet or anywhere else. Since this crash happens only sporadically it will be a while until I get confirmation that the following is a solution: if (turn_sock->sess) { pj_turn_session_on_rx_pkt(turn_sock->sess, data, size, &parsed_len); } Does anyone have a better suggestion? I managed to capture the logs of what's happening immediately before the crash, but due to the asynchronous nature of the logger it might have missed a couple of statements. Here is the stack trace: Crashed: Thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000078 0 Application 0x100a9eaf4 pj_turn_session_on_rx_pkt (turn_session.c:1154) 1 Application 0x100aa01e8
