Hello,

this one seems from the main process during the shut down cleanup. Perhaps the core from main process overwritten the one from worker process. Can you enable one core file per process in Solaris? In linux is possible via:

echo "1" > /proc/sys/kernel/core_uses_pid

Then you have to reproduce the case and get the backtraces from each corefile.

Cheers,
Daniel

Hello,

from the log messages, you got a core dump file. Locate it (should be in / if you haven't specified -w 'path' or solaris does not have a special directory for corefiles) and get the back trace:

gdb /path/to/kamailio /path/to/corefile

Then inside gdb execute 'bt full' and send the output here.

Cheers,
Daniel

hello,

I am running kamailio 3.2.2 on Solaris 10 64 bit and I am getting a core dump on this statement:

   $ru = "sip:" + $rU + "@" + $sel(cfg_get.registrar1.server_ip)
                                + $sel(cfg_get.registrar1.server_port);

Here is how the variable is defined:

registrar1.server_ip = "xxx.xxx.xxx.xxx" desc "Registrar server IP address"
registrar1.server_port = "5080" desc "Registrar server Port"

Here is the output from the logs with debug:

Here is the full route code:

route[TO_REGISTRAR] {

        # check if Registrar server's IP is defined

        if (strempty($sel(cfg_get.registrar1.server_ip))) {

                xlog("SCRIPT: REGISTRAR - registrar1.server_ip not defined\n");
                return;

        }

        $ru = "sip:" + $rU + "@" + $sel(cfg_get.registrar1.server_ip) + ":"
                                + $sel(cfg_get.registrar1.server_port);

        route(RELAY);
        exit;

} # End of TO_Registrar Route

I am trying to setup the proxy server to route all registers requests to another kamailio server

Thanks

Nathaniel
