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

Hi Jason,

Pls. find the configuration in attachment (complete /etc/kamailio).

I'm iteratively trying to understand and configure kamailio as S-CSCF, later probably as P-CSCF and even later as I-CSCF and so on. Thus gaining know how.

I kept as close as possible to the cookbook https://www.kamailio.org/wiki/tutorials/ims/installation-howto

I could not find information about howto create MySQL database for S-CSCF and was sure I did only need the MySQL database if I wanted to have a presence server.

Thus I commented out the DB_URL and DB_URL2 in scscf.cfg.

Maybe this is the reason? But should not lead to a crash, imho :)

Kind regards,

Christoph

Hi Christoph,

Can you pls send your cfg file? Also, are you not using DB mode?

Cheers

Jason

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

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 [email protected], registered user [email protected], deregistered user [email protected]

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
