Hi Jason,
 
Sorry for delay, but I did like to try Carsten's proposal, before I send you the GDB traceback.
 
Now I installed the same packages but from kamailio-4.4.1-1.1, did not change the config and repeated the test - same result.
 
tshark, level 2 logs and GDB traceback in attachment of this mail.
 
I found two cores from the same time, only one fits to kamailio.pid, but I did two backtraces.
 
Two suspects:
   1)  deactivated the dispatchers (want to activate in later step)
   2)  deactivated presence DB (want to activate in a later step)
 
Thanks for help,
Christoph

Betreff: Re: [SR-Users] S-CSCF (kamailio) crashes after deregistration of client

Will look into this for you later today. Any chance of a gdb backtrace in the meantime?

I'm experimentally using kamailio 4.4.0-12.1 as an S-CSCF, connected via Cx to an HSS and connected via Mw to a Zoiper Client.
 
I installed following RPMs:
kamailio-xml-4.4.0-12.1.x86_64
kamailio-4.4.0-12.1.x86_64
kamailio-debuginfo-4.4.0-12.1.x86_64
kamailio-mysql-4.4.0-12.1.x86_64
kamailio-ims-4.4.0-12.1.x86_64
kamailio-tls-4.4.0-12.1.x86_64
kamailio-presence-4.4.0-12.1.x86_64
 
and copied config from kamailio-4.4.0_src.tar.gz
examples/scscf
 
Modified config (see attached etc_kamailio.tar.gz)
 
Prepared Zoiper client, prepared HSS
 
Then started S-CSCF (kamctl start), registered user xaver@vict-ims.net, registered user yvonne@vict-ims.net, deregistered user yvonne@vict-ims.net
 
After some time S-CSCF gets signal 11 and stops, I guess its some timer expiring thats the reason (tshark and kamailio level 3 logs in attachment) ---> who's wrong? Is it a bug in kamailio? Is it a wrong config?
 
Thanks for help
