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
