CLX Driver High Read Function Exceptions High CPU Usage

[StephenSDH]

I am having exceptions that causes my application to stop logging and high CPU usage.  Compactlogix processors and CLX driver.  Both exceptions are inside the Read function.  I have it in Try Catch blocks, but it appears to not always recover and eventually the application stops reading and goes to high CPU usage.   I can duplicate it and I have a test PLC set up here. 

Stripped down Logic (2 Machines (PC2 and PC3), logic executes at a 5 second interval for logging)

                ' Get Machine Values
                PC3_LineRunning = PC3PLC.Read("DCS.LineRunning")
                PC3_OperatorPresent = PC3PLC.Read("DCS.OperatorPresent")
                PC3_BlenderRunning = PC3PLC.Read("DCS.BlenderRunning")
                PC3_MachineCycle = PC3PLC.Read("DCS.MachineCycle")
                PC3_ProductCode = PC3PLC.Read("DCS.ProductCode")
                PC3_WaitingMold = PC3PLC.Read("DCS.WaitingMold")
                PC3_BackedUp = PC3PLC.Read("DCS.BackedUp")

                ' If Machine Cycle is set then Turn Off
                If PC3_MachineCycle Then
                    PC3PLC.Write("DCS.CycleLogged", 1)
                End If

It looks like this would occur if a com error came back. I put some additional checks in to catch this situation. It will be part of the next release that will be posted withing the next few days.
