Hello Ali,
the problem is that TCP depends somehow on forking processes. If you can't switch to
UDP, have you tried to just connect with gdb to the PID of the TCP process? Configure just
one TCP child to make this easier for you to catch the right one.
Cheers,
Henning

Hello Henning,
Thanks for your help. I test both -D and -DD option when running kamailio in gdb.
When running kamailio with -D it doesn't accept any request on TCP, and when I run
with -DD option gdb doesn't stop on the break point.
In summary:
$ sudo gdb kamailio
(gdb) b isc_from_as
(gdb) r -f /path/to/kamailio.cfg -D ---> doesn't accept TCP requests
(gdb) r -f /path/to/kamailio.cfg -DD ----> gdb doesn't stop on break point
Regards,
Ali

Hello Ali,
have a look to the kamailio binary parameter and the children parameter in configuration.
You can actually start kamailio with (almost) no forking.
You will get a lot of debugging information if you enable the kamailio debugging in the
cfg.
If you want to debug only the internals of the core or a specific Kamailio module, there
is also a debugger module available that can be useful to debug only certain parts of the
server. You can also set breakpoints at certain points in the cfg, or dump internal state
with it.
Cheers,
Henning

Hi all,
I want to trace function calls in a kamailio module, e.g. ims_isc module. I installed
kamailio-dbg package and started the kamailio with gdb: `gdb kamailio` I also set break
point on target function, but it seems gdb doesn't stop on that break point.
How should I start gdb and set break points? it seems gdb couldn't handle kamailio
child processes that forked in start.
Regards,
Ali
