After a while, I am getting a ERROR #15 calling FSUIPCConnection.Process().  I'm at a bit of a loss where the memory is going here... 

FSUIPC = 5.131

FSUIPC Client DLL = 3.1.3.302

Added the below:

            Console.WriteLine(FSUIPCConnection.Statistics().ConnectionOpenFor.ToString)
            Console.WriteLine(FSUIPCConnection.Statistics().ProcessCount.ToString)
            Console.WriteLine(FSUIPCConnection.Statistics().ProcessLast.FsuipcMemoryFilePercentFull.ToString)

I can clearly see the FsuipcMemoryFilePercentFull increasing gradually until it eventually reaches 100%.

Commenting out all references to taking the PositionSnapShot, and not calling the GetPositionSnapshot, I can see that the FsuipcMemoryFilePercentFull does not increase any more.

Is there a leak in GetPositionSnapshot perhaps?

Yes there was. One of the internal offsets wasn't getting removed.

Thanks for the report.

I've just uploaded 3.1.5 to NuGet which should fix this.
