Thank you -- I've recompiled and enabled the memory debug. I have the log file from the whole experience available here:
http://netbrains-misc.s3.amazonaws.com/opensips/opensips.log (note - real phone numbers and domain names in the log have been replaced with placeholders) The key item seems to be: CRITICAL:core:qm_free: freeing already freed pointer, first free: logic.c: process_bridge_200OK(740) - aborting Although this appears to be after we've already decided we're going to crash, as I see "INFO:core:cleanup: cleanup" and "NFO:core:handle_sigs: child process 24788 exited by a signal 6" above this part of the log. Also worth noting is the existance of "CRITICAL:b2b_logic:b2bl_drop_entity: we should never end up here" throughout the log. Also, here's the stack trace at crash time. Note that there were two core files generated for the same crash, so this is the backtrace from each: #0 0x0000003564c328a5 in raise () from /lib64/libc.so.6 #1 0x0000003564c34085 in abort () from /lib64/libc.so.6 #2 0x000000000049d370 in qm_free () #3 0x00007ffccb253804 in process_bridge_200OK () from /usr/lib64/opensips/modules/b2b_logic.so #4 0x00007ffccb254ba2 in b2b_logic_notify_reply () from /usr/lib64/opensips/modules/b2b_logic.so #5 0x00007ffccb2565e1 in b2b_logic_notify () from /usr/lib64/opensips/modules/b2b_logic.so #6 0x00007ffccb47a7a7 in b2b_tm_cback () from /usr/lib64/opensips/modules/b2b_entities.so #7 0x00007ffccc744b71 in run_trans_callbacks () from /usr/lib64/opensips/modules/tm.so #8 0x00007ffccc74fa12 in local_reply () from /usr/lib64/opensips/modules/tm.so #9 0x00007ffccc750cc5 in reply_received () from /usr/lib64/opensips/modules/tm.so #10 0x00000000004266da in forward_reply () #11 0x0000000000452ad8 in receive_msg () #12 0x0000000000496c95 in udp_rcv_loop () #13 0x000000000042d763 in main () #0 0x0000003564c328a5 in raise () from /lib64/libc.so.6 #1 0x0000003564c34085 in abort () from /lib64/libc.so.6 #2 0x000000000049d370 in qm_free () #3 0x00007ffccb25a003 in b2bl_delete () from /usr/lib64/opensips/modules/b2b_logic.so #4 0x00007ffccb25a3d5 in destroy_b2bl_htable () from /usr/lib64/opensips/modules/b2b_logic.so #5 0x000000000046dbf2 in destroy_modules () #6 0x00000000004298a1 in cleanup () #7 0x000000000042a360 in handle_sigs () #8 0x000000000042db66 in main () I am unfamiliar with this codebase. Can anyone garner anything useful from the logs?
