Hi Daniel,
This happens randomly. It is not a testbed and never reproducible on the
test server. I can still give you access if you wish to analyse the core
files to check whats happening here exactly.
It simply feels like on heavy load the evapi socket gives up. Earlier I was
running 5.0.2 and in that kamailio would get stuck by not sending any async
events on evapi socket. Not even the evapi:connection-closed event gets
triggered. After I upgraded to latest stable version (5.1.5), it at least
started crashing. Here are two core dumps put onto pastebin.

Thanks for all the support,

Hello,
are you able to reproduce it somehow? Or just happens randomly?
Is it on a testbed where I could get access to investigate the corefiles?
If not, then I will ask for more details from cores over email, first would
be 'bt full' for both cores and 'p *dead_cell' for the second one.
Cheers,
Daniel

Hi Daniel,
Have got these core dumps. Let me know if I should be doing a bt full.
I'll pastebin and send. Thanks,

Hello,
the backtrace doesn't show any hint about kamailio, only from closelog()
up.
It may be the core generated by shutdown procedure, have you enabled one
core file per pid/process? If not, do it and reproduce the issue again, you
may get two core files, one being the runtime issue and the other one from
shutdown procedure, which likely is an effect of the other one. The one
from the runtime is more relevant.
Cheers,
Daniel

Hello,
I'm using kamailio 5.1.5 with evapi. I have a node.js connecting with
kamailio evapi to which I send events and also consume events based on
which I do the routing. I have 8 evapi workers defined in the config.
The problem is that kamailio randomly crashes on high load. I'm assuming
that it is related to the evapi module as rest of the config is pretty
straight forward. I could get a core file and here's the core dump:

Any help in this regards is would allow me to identify the reason of the
