[OpenSIPS-Users] /etc/init.d/opensips restart returns OK when opensips is down...

[Dave Singer]

Toyima,

What I've done to deal with errors on a restart is to copy the config
to a temp, replace a couple things like fifo file and ports, start it
with foreground option, piping output to check for errors. The group
is backgrounded with & and the init script waits for 2 sec. If bk
process is still running and no errors, it is killed and real restart
is proceeded with.

I posted my init script a few months back in the list if you want more details.
Be cautious of the script return value as restart failure may be just
that the config was bad and opensips was not restarted but still
running old config, you may not want to have HA kick to other server.
