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 Michael
