I have a NW65SP5 Server which is one of the most reliable we have, but it
can be easliy driven against the wall buy simply downloading a large file,
lets say 1 GB using the Portal. I remember we had the problem in the past
also on this server so it is not a SP5 problem.
Downloading large files via NCP Client oder SSHD is not a problem.

Has anyone a clue or a solution to that?
