[SR-Users] TLS problems

Fri Jan 22 10:13:45 CET 2010

Hi Klaus!

Yes, the crash happens everytime (and immediately) when I push the
"Register"-Button in snoms web-gui.

I attached the backtrace-file, but until now I did not rebuild kamailio with
-DDBG_QM_MALLOC. Please let me know if it's necessary.

regards
Andreas

Hi Andreas!

Maybe this is the same bug I reported yesterday. Unfortunately I can not 
reproduce the crash anymore.

Does the crash happen everytime?

Kamailio produced a core dump:
 >  0(6257) ALERT: <core> [main.c:725]: core was generated

So please send a the backtrace:
# gdb kamailio /path/to/corefile
 > bt

Location of the core file is usually / or /tmp or the kamailio's working 
directory. Use
# cat /proc/sys/kernel/core_pattern
to find the exact location of the core dump.

Further, it might be useful to enable memory debugging:
- in Makefile.defs use -DDBG_QM_MALLOC instead of -DF_MALLOC and 
rebuild/reinstall kamailio
- set higher loglevels in kamailio.cfg
   memlog=3
   memdbg=3
   debug=3
   modparam("tls", "tls_log", 3)

Note: this excessive logging makes kamailio start/stop real slow and 
logfile will increase rapidly (might fill up your hard disk)
