The backtraces are incomplete because you need to install kamailio
debugging symbols -- there is a package named kamailio-dbg or so that
has to be installed.
Then it seems to be some protection on the system preventing loading
other libraries, based on the content of the file you sent. Apparently
you have to disable this security protection by adding:
set auto-load safe-path /
line to your configuration file "/root/.gdbinit".
Then reproduce the case and grab again the kamctl trap. After that you
can eventually revert the change in /root/.gdbinit.
Cheers,

Thanks Daniel for your response.
Please find attached the "kamctl trap" output file, we were able to
recreate that issue again.
Traffics are not blocked as I can see messages are received on the
kamailio listen interface by using sngrep tool.
Also, the pike module is not in effect as WITH_ANTIFLOOD is not
defined in the default configuration.
Thanks,
Uttam

Hello,
install gdb and when the kamailio stops responding send here the
file generated by the next command:
kamctl trap
The path to the file is printed when the command is executed. Note
that it can take a bit to generate the file, if you have a lot of
kamailio processes. The file contains the gdb backtrace for each
process, showing what they do at that moment.
For a few of other hints, be sure you don't block the traffic with
the firewall/fail2ban or with pike module in kamailio.cfg.
Cheers,
Daniel

Hi,
We are using Kamailio with Jitsi client where we observed
sometimes Kamailio stops responding to sip messages. As a result,
my Jitsi client goes offline and never back online. Also in the
Kamailio syslog there are no error logs(debug enabled) related to
this issue. As a temporary workaround, we had to restart the
Kamailio server all the time.
Does anyone observed a similar issue and can suggest any resolution.
Kamailio version:-
