Hi Daniel, Andrew

I've just tested the patch and kamailio crashes when the redis server is
stopped. This is what I could get:
-From the logs:
Feb 17 06:33:32 r-gate-test ./kamailio[23812]: ALERT: <core> [main.c:751]:
child process 23819 exited by a signal 11
Feb 17 06:33:32 r-gate-test ./kamailio[23812]: ALERT: <core> [main.c:754]:
core was generated
Feb 17 06:33:32 r-gate-test ./kamailio[23812]: INFO: <core> [main.c:766]:
INFO: terminating due to SIGCHLD

-An the backtrace:
(...)
Core was generated by `./kamailio -f ../etc/kamailio/kamailio.cfg'.
Program terminated with signal 11, Segmentation fault.
