Hello, One of my FS instances has crashed with a coredump. I copy/past the output of bt and bt full. Should I open an issue on a website? Is there any sufficient information to diagnose? Here is the bt output: #0 switch_core_session_get_channel (session=0x0) at src/switch_core_session.c:1357 #1 0x00007f0418ff8ce9 in sofia_update_callee_id (session=0x0, profile=0x165a010, sip=0x7f03d0500e68, send=SWITCH_TRUE) at sofia.c:1086 #2 0x00007f0418ffee55 in our_sofia_event_callback (event=nua_i_update, status=200, phrase=0x7f03d0564700 "OK", nua=0x7f03f40120f0, profile=0x165a010, nh=0x7f0391a7e450, sofia_private=0x7f0308a21620, sip=0x7f03d0500e68, de=0x7f03f402cd20, tags=0x7f03d05646f0) at sofia.c:1594 #3 0x00007f04190044fb in sofia_process_dispatch_event (dep=<value optimized out>) at sofia.c:1983 #4 0x00007f0419005266 in sofia_msg_thread_run (thread=<value optimized out>, obj=0x7f0418f9aad8) at sofia.c:2031 #5 0x00007f041c4f49bb in dummy_worker (opaque=0x1642520) at threadproc/unix/thread.c:151 #6 0x0000003f38e079d1 in start_thread () from /lib64/libpthread.so.0 #7 0x00000030f40e8b6d in clone () from /lib64/libc.so.6 And the bt full: (gdb) bt full #0 switch_core_session_get_channel (session=0x0) at src/switch_core_session.c:1357 __PRETTY_FUNCTION__ = "switch_core_session_get_channel" #1 0x00007f0418ff8ce9 in sofia_update_callee_id (session=0x0, profile=0x165a010, sip=0x7f03d0500e68, send=SWITCH_TRUE) at sofia.c:1086 channel = <value optimized out> passerted = <value optimized out> name = <value optimized out> number = <value optimized out> tmp = <value optimized out> caller_profile = <value optimized out> dup = <value optimized out> event = <value optimized out> val = <value optimized out> fs = <value optimized out> lazy = <value optimized out> name_var = <value optimized out> num_var = <value optimized out> __PRETTY_FUNCTION__ = "sofia_update_callee_id" __func__ = "sofia_update_callee_id" #2 0x00007f0418ffee55 in our_sofia_event_callback (event=nua_i_update, status=200, phrase=0x7f03d0564700 "OK", nua=0x7f03f40120f0, profile=0x165a010, nh=0x7f0391a7e450, sofia_private=0x7f0308a21620, sip=0x7f03d0500e68, de=0x7f03f402cd20, tags=0x7f03d05646f0) at sofia.c:1594 tech_pvt = <value optimized out> auth_res = <value optimized out> session = 0x0 channel = <value optimized out> gateway = 0x0 locked = <value optimized out> check_destroy = 1 __func__ = "our_sofia_event_callback" __PRETTY_FUNCTION__ = "our_sofia_event_callback" #3 0x00007f04190044fb in sofia_process_dispatch_event (dep=<value optimized out>) at sofia.c:1983 de = 0x7f03f402cd20 nh = 0x7f0391a7e450 nua = 0x7f03f40120f0 profile = 0x165a010 sofia_private = <value optimized out> #4 0x00007f0419005266 in sofia_msg_thread_run (thread=<value optimized out>, obj=0x7f0418f9aad8) at sofia.c:2031 de = 0x0 pop = 0x7f03f402cd20 q = 0x7f0418f9aad8 my_id = <value optimized out> __func__ = "sofia_msg_thread_run" #5 0x00007f041c4f49bb in dummy_worker (opaque=0x1642520) at threadproc/unix/thread.c:151 thread = 0x1642520 #6 0x0000003f38e079d1 in start_thread () from /lib64/libpthread.so.0 No symbol table info available. #7 0x00000030f40e8b6d in clone () from /lib64/libc.so.6 No symbol table info available.
