ok, maybe I'm completely on the wrong track. I have had some strange=20
behaviours on a testimplementation of a new protocol, which sends keep aliv=
packets periodicly. I experienced, that the kernel crashes (without direct=
connection to my code and sadly without a panic or trace). When I used a=20
static version of my periodicly called function, this problem disappeared.=
But when there is no real (fundamental) difference between static and=20
"normal" function calls, I really need to have a look at my code again!

The problem takes place, when I copy a lot of data e.g. via "scp". It's rea=
hard to debug things like these, does someone had a similar problem and som=
ideas how to recognize/debug them!?
