[SR-Users] Kamailio auto restart if stopped

[JR Richardson]

Hi All,

Just had a strange occurrence where kamailio has been up and running
fine for several months and just died with a strange error:

root at sip-router3:~# kamailio -V

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.
