Hello,

the error message from dispatcher is not relevant for runtime, it is saying that you have to set some parameters to dispatcher module (those with avp names) because you use ds_next_dst()/ds_next_domain() -- without those parameters, you can't do re-routing using failure_route and dispatcher functions.

From the logs, it is nothing showing the cause of the issue, could be your own modules or something else.

Try to generate a corefile and then get the backtrace with gdb. To generate the corefile:

 - run "ulimit -c unlimited" in the terminal where you start kamailio
 - run kamailio as root user
 - reproduce the issue
 - there should be a log message saying that the "core was generated"
 - get the output of "bt full" from gdb inspecting the core file

Cheers,
Daniel

Hi Everyone,

I am trying to start kamailio 5.1.4 with two own modules. After /etc/init.d/kamailio start , I am getting one error of the dispatcher module and bunch of warrnings because of missed reply and failure routes.

The first error before crashing is:

ERROR: dispatcher [dispatcher.c:814]: ds_warn_fixup(): failover functions used, but required AVP parameters are NULL -- feature disabled


Later on, when I am trying to register a user (from a soft phone) i am getting the following:

Regarding to the first error of the dispatcher module i could not find out which calibration i can follow with its parameters to get rid of this error.

Regarding the jasonrpcs and the last two erros, here are my configuration in kamailio.cfg:

#/* set the path to RPC fifo control file */
modparam("jsonrpcs", "fifo_name", "/tmp/kamailio_jsonrpc.fifo")
modparam("jsonrpcs", "fifo_mode", 0755)
modparam("jsonrpcs", "fifo_group", "kamailio")
modparam("jsonrpcs", "fifo_user", "kamailio")


#/* set the path to RPC unix socket control file */
modparam("jsonrpcs", "dgram_socket", "/tmp/kamailio_rpc.sock")
modparam("jsonrpcs", "dgram_mode", 0755)
modparam("jsonrpcs", "dgram_user", "kamailio")
modparam("jsonrpcs", "dgram_group", "kamailio")

I think the root cause is even beyond the dispatcher and jsonrpcs modules setting.

Please check the attached where you can find my complete log file after starting Kamailio.

Best regards
Abdulaziz
