Brad, this is very common. WE have something similar to this. We have added one thing. Each instances of our application has a keepalive timer: It updates a datetime field in the log every minute.

If analyzing the log and you find a record where the keepalive datetime stamp is more than a two minutes ago, it is safe to assume the application instance has crashed or got locked.

BTW, we are using the date and time from the server to do this to avoid problems on PCs with incorrect dates and times
