Hello Andi.

Thanks for your response but your guess is (at least partially)
wrong. This is happening with HP-UX systems.

I'm used to have a couple of dtterm/hpterm windows on our HP-UX
systems. After uprading to 2.0.34 they are closed after some
period of inactivity. This is probably related to keep alive handling.

I remember i saw a message somewhere (which i can't find anymore)
that this is a side effect of a 2.0.34 TCP change. The quick fix
was to replace the return value at the end of a tcp_* function.
However i can't remember the details and this is getting
annoying ...

Thanks for your help
