[OpenSIPS-Users] opensips HA resource script (for Heartbeat)

[Alexandr A. Alexandrov]

Hi, All.

This is an issue of writing a correct script, nothing more. :-)
There are several possibilities, strating from simple process lookup 
(like pgrep -f opensips), ending using MI from such a script.

I will make my opensips valid, was just wondering if someone already 
invented that bicycle. :-)
