> We've been noticing a random freeze on exit for 30 seconds.  The frequency is different per machine, but it happens about 10-30% of the time, sometimes more.  We've traced it down to TcpTransport.Close(), in this block:
> {noformat}
> if(null != readThread)
> {
> 	if(Thread.CurrentThread != readThread && readThread.IsAlive)
> 	{
> 		if(!readThread.Join((int) MAX_THREAD_WAIT.TotalMilliseconds))
> 		{
> 			readThread.Abort();
> 		}
> 	}
> 	readThread = null;
> }
> {noformat}
> We're running this in the Unity game engine, which run C# script in a Mono environment.
> I understand that reproducing this on your end would be difficult, but I'm reporting this in the hopes that I can gain some insight why this is happening.
> - What thread is this code waiting for?
> - What would be some of the causes of the deadlock?
> No messages are being sent or received.  It's basically starting up and closing down.
> Our temporary workaround is to reduce this wait time from 30 seconds to 5 seconds, but I'd like to eventually find a cause.
> Thanks
