Frame 0 is missing all the details. The crash seems to be in a module that uses dialog
module. Can you list here the loadmodule statements in your config?

A side note first: format the messages you add and put the code snippets as code blocks --
see the github markdown format docs. It is easier to read and analyse the comments.
I spotted only nat_traversal module that would register callbacks to dialog. For what are
you using it?

Hello,
I have changed the order i have declared the modules and just brought "mi_fifo"
to the top. The crash was however there but now frame 0 has some data.

You can reproduce it every time?
Can you try without nat_traversal module (comment its related lines)?

yes i can reproduce this everytime.
removing the nat_traversal module..requires loads of changes in my cfg.
however what I have noticed is, changing the parameter "enable_tls=yes" to
"enable_tls=no" does not cause a crash. but i want to use tls as I would be
using wss.

Can you start with command line parameter '-x qm'? Add to the rest of parameters
you have.
Then look in the syslog file for all messages printed by kamailio since it was started and
see if there are some relevant ones before the crash.

Yesterday was public holiday in most of Europe and next days is the Kamailio World
Conference, with many Kamailio people participating, therefore expect lower activity on
the forums.
The core you got is not the good one, because it is the shutdown procedure. You have to
enable one core file per process and then see if you get more than one core file. If yes,
then paste here the backtrace for each core file.

Can you go with in the frame 2 of the core that has:
```
#2 0x00007f25fec371e7 in keepalive_timer (ticks=65354259, data=0x0) at
nat_traversal.c:1597
```
Then do the following gdb commands:
```
frame 2
info locals
p *slot
```

So the slot is not a valid pinter. Can you print in the same frame 2:
```
p nat_table
p *nat_table
```

The slots field has invalid pointer value, so I suspect a buffer overflow somewhere, but
not revealed by the logs. Could be in the nat_travesal, which I expect not much used as I
know lots using nathelper instead.
Would require investigating in more deep the core files, longs and eventually reproducing
it while troubleshooting. Would it be possible to get access to the system via ssh or for
you to build a replica to another server in the cloud where the access can be provided
easier?

It seems to still be a conflict of openssl lib initializer -- kamailio does it and then
mongo c driver messes it somehow. I would need to dig into mongo c driver code, but that
can take a while.
I compiled mongo c driver 1.3.5 (latest stable version) without ssl support and all seems
to run fine. Perhaps this would be ok for you to run for a while.
