[SR-Users] Core Dump from select stmt

[Daniel-Constantin Mierla]

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
