TCP Monitors causing issues.

Hello,

We have this application that is pretty old. We installed it and configured it on new servers and trying to load balance with the F5.

With the TCP monitor, we are getting errors in the application log, but the monitoring is working fine. However, it is filling the logs up.

 Authentication failed because the remote party has closed the transport stream. 

This has happened in other applications and sometimes I can switch to tcp_half_open monitor and that fixes the problem. However, with this application, when I switched to tcp_half_open the Application restarted itself. It takes about 10 minutes to restart, and then it would come up for a moment and then restart itself again. This was the error being seen when it started back up.

Application: PRTasS.exe
Framework Version: v4.0.30319

Apparently, this was a run-time .Net error:

Is there anyway I can customize a monitor or is there another monitor I could use that would monitor the app without causing this mayhem?

Is there anything else I could to fix this? Thoughts/Suggestions???

Thanks.
