Sorry for the multiple messages. disregard the previous two. I'm having this strange crash on one of pjsip's threads running on ios. the pbx is connected and no call is being made. Can anyone suggest an idea of what could cause this? Here is the call stack from the thread. Here is a better callstack to read: 10Thread 10 Crashed 0 ... libsystem_kernel.dylib __pthread_kill + 8 1 libsystem_c.dylib pthread_kill + 58 2 libsystem_c.dylib abort + 94 3 libsystem_c.dylib basename 4 Yalo regc_cb + 1464130 5 Yalo regc_tsx_callback + 1443814 6 Yalo mod_util_on_tsx_state + 1382432 7 Yalo tsx_set_state + 1372880 8 Yalo tsx_on_state_proceeding_uac + 1374064 9 Yalo tsx_on_state_calling + 1373742 10 Yalo pjsip_tsx_recv_msg + 1379112 11 Yalo mod_tsx_layer_on_rx_response + 1371272 12 Yalo pjsip_endpt_process_rx_data + 1336204 13 Yalo endpt_on_rx_msg + 1338058 14 Yalo pjsip_tpmgr_receive_packet + 1348532 15 Yalo on_data_read + 1358848 16 Yalo ioqueue_on_read_complete + 1565492 17 Yalo ioqueue_dispatch_read_event + 1553772 18 Yalo pj_ioqueue_poll + 1554374 19 Yalo pjsip_endpt_handle_events2 + 1336478 20 Yalo worker_thread + 1490950 21 Yalo thread_main + 1557524 -------------- next part -------------- An HTML attachment was scrubbed...
