Server heartbeat
You can try to implement a tool that will not only solve this problem, but also has potential to address many other areas associated with building a high availability infrastructure. The tool I'm referring to is called "heartbeat".
Heartbeat is a publicly available package written by Alan Robertson. Heartbeat monitors system for certain event and can take actions based on those events. It can look to see if a particular service is running and if it isn't it can send an alert and/or automatically restart the service on a different machine. It also has the capability of transferring ownership of a shared IP address between nodes in a "heartbeat cluster".
Just do a google search for configuration details. It takes a bit to configure but it is a really cool solution for any HA environment.
