Hi Christian,
could you also send the crashing line from gdb ? (just printed when entering gdb). Also could you try with nathelper?
First line of gdb is:
Core was generated by `/opt/openser-devel/sip-server/openser -f /etc/openser-cvs/openser.cfg -w /var/t'. Program terminated with signal 11, Segmentation fault.
I also tried it with the nathelper nat ping settings:
# -- nathelper params -- modparam("nathelper", "rtpproxy_disable", 1) modparam("nathelper", "natping_interval", 30) modparam("nathelper", "sipping_from", "sip:ping@sip1.unc.edu")
# -- mediaproxy params -- modparam("mediaproxy","natping_interval", 0)
The server seg faults exactly the same as with the mediaproxy nat ping feature:
Core was generated by `/opt/openser-devel/sip-server/openser -f /etc/openser-cvs/openser.cfg -w /var/t'. Program terminated with signal 11, Segmentation fault.

Hi Christian,
getting a backtrace will be very, very helpful. be sure the you are using exactly the same binaries as the ones generating the core file.
Also, could you describe the scenario leading to the crash? also set debug=9 and the log will be very useful.
Ok, I got some more insights now (I took the wrong binary for the backtrace). The whole issue seems to be related to the nat_pinging function of the mediaproxy module in combination with db_mode=3. But first the backtrace:
#0 0x00b2b392 in get_all_db_ucontacts (buf=0x8135e20, len=252, flags=1) at dlist.c:150 #1 0x002cfcf0 in pingClients (ticks=30, param=0x0) at functions.h:44 #2 0x08088afb in timer_ticker () at timer.c:141 #3 0x08063e94 in main_loop () at main.c:988 #4 0x0806504c in main (argc=7, argv=0xbfff8de4) at main.c:1473
And these are my nat_pinging settings:
# -- nathelper params -- modparam("nathelper", "rtpproxy_disable", 1) modparam("nathelper", "natping_interval", 0)
# -- mediaproxy params -- modparam("mediaproxy","natping_interval", 30)
If I disable the nat pinging by setting the interval 0 the server just runs fine with db_mode=3. I haven't tested yet if the nathelper nat_pinging causes the same issues as the mediaproxy one.
This is what the debug=9 log tells (I filtered the log for messages from the process the crashes):

Thanks a lot for looking at that, Christian

Hi all,
Running openser (CVS HEAD) with usrloc:db_mode=3 causes it to crash repeatedly after 15 secs or so. The core dump does not say much except

The openser log looks like:
ERROR: receive_fd: EOF on 16 child process 18101 exited by a signal 11 core was generated
I also don't see any mysql errors. The last mysql query issued by openser before dying is always
Query delete from location where expires<'2006-06-05 16:03:17' (only the timestamp changes)
Deleting all location table entries before starting up openser does not help either. Is there something special I have to consider when running openser in DB-only mode?
Thanks for any help, Christian
