OpenSSH server stops returning data from a server module

[Norbert Sendetzky]

Hi all

I believe I've finally found the problem, why the OpenSSH Server 
stopped forwarding of the replies from the server module!

The problem seems to be that the server module writes a lot of debug 
messages to stderr and the server can handle only a certain amount. 
After I changed the location where the messages are written to from 
stderr to a file descriptor pointing to a real file, everything is 
fine. Can someone please verify my observation?
