Hello,
for this specific crash issue, just upgrade to 4.1.3, it should be fixed
there.
For automatic restart, look at 'monit' tool - open source, available in
most distros. It can supervise processes by pid and restart, and, iirc,
in its docs the should be an entry for openser. Anyhow, is rather
simple, the basic cfg for kamailio in monit is something like:
check process kamailio with pidfile /var/run/kamailio/kamailio.pid
start program = "/etc/init.d/kamailio start"
stop program = "/etc/init.d/kamailio stop"
if 5 restarts within 5 cycles then timeout
Also, it can do sip keepalives, being able to discover when kamailio is
stuck.
Cheers,
Daniel

Not sure what that means, memory leak? I started started it right back
up with no indication of a problem. Running Kamailio for many years,
I have never had an instance of it just shut down before. So I'm
wondering if there are any safe scripts that check the running process
for kamailio and restart if automatically if not running?
I dug around a bit but not seeing any hits for auto start kamailio scripts.
And another question would be if this occurrence of shutting down
should be of concern or not?
Thanks.
JR
