Unfortunately, I am currently very busy (the end of a year is always a hot time), so I can't promise to handle it in a few days. I don't see an easy way to fix the bug, so it might need quite a bit of time to research.

Your main service will still use duplex tcp, while the update service will be simplex tcp-based. OK - that is a nice workaround. Do you think, that you Need a Long time to resolve the Problem? If you can fix it in few days then I will wait on the fix. But if you think you Need much weeks or months then I will implement the Workaround [Less]
