Hello,
can you install the kamailio-dbg package to get access to debugging
sysmbols? Once that package is installed, get the backtrace again and
send it here.
Cheers,
Daniel

The scenario is to call a remote which is started. After starting the
regisration, the call is presented, then kill the app, then started
again, call is presented, wait while ringing....
After a few times, kamailio crashs.

This is during shut down clean up. Have you stopped kamailio
manually? If not, aave you got more than one core file? If not,
enable one core file per process.
Cheers,
Daniel

It seems related to tsilo module and tm module:

I have seen some commits related to tm module after release 4.3.1
Should it work better in 4.3.2 ?

Hello,
do you get other error messages in syslog before the one
"CRITICAL: ..."?
It is hard to say it is from something already known or new.
Right now there is an open issue for saving dialog variables
in database that was not yet sorted out. Another one related
to tm and memory manager, reported after 4.3.1, got a safety
fix. Apart of these two, I don't remember any active crash
report for the moment.
If you get it very often, then it should be easy to catch and
troubleshoot properly. Can you run it so it generates a core
file?
The easiest way is to run it as root, with 'ulimit -c
unlimited' executed before starting kamailio.
Can you share what operating system are you using and exact
version of kamailio (output of kamailio -v)?
Cheers,
Daniel

After upgrading to kamailio 4.3.1 and
modifying the config,
I get this crash very often:
...
CRITICAL: <core> [pass_fd.c:275]: receive_fd(): EOF on 21
ALERT: <core> [main.c:728]: handle_sigs(): child process
9341 exited by a signal 11
ALERT: <core> [main.c:731]: handle_sigs(): core was not

INFO: <core> [main.c:794]: sig_usr(): signal 15 received
INFO: <core> [main.c:794]: sig_usr(): signal 15 received
...
Is it known ? or may be related to my config ?
Thank you
Thibault
