#21 Socket Closed - OPC Server

[JMekala]

I get the following exception, seemingly at random.
The problem generally happens when the connection is open and has been in use for a few minutes (anywhere from 7 sec).

Any ideas about what is going wrong here or how I can fix it would be greatly appreciated.

Log file attached. See "java.io.IOException: Socket Closed" at line 10299.
