Unfortunately I do no longer have access to the system, so we would have 
to stick to a theoretical approach :-(. Maybe an increase in 
SendBufferSize would mitigate the Issue, but in my opinion the code 
should be written that it could not block even the send buffer is full.
Or The listener thread should dispatch the closing to a worker thread, 
so it gets not distracted from handling new connections.
