This latest version of SoftGrid 4.1 will fix that annoying issue when you have two servers behind a Load Balancing device. I tried this today and sure enough the Event Logs look much better.
Errors in Event Viewer (From Microsoft)
The log level of the “Error reading from socket” message is now Debug. Therefore, the message does not appear in the Sft-server.log and the Windows event log at the default log level when you use SoftGrid Virtual Application Servers together with a hardware load balancer.
