Sorry my english is not very good. The server works fine for some 10 hours and
then I do some things on the host (like xm console .. or tar -xvf ...) then the
server crashed. ping works fine, but you can't connect ssh. If I on the
console, I can do nothing, I must shutdown the server hard..! If you have
questions you can mail me at kkuik@xxxxxxxxxxxxxxxxxxxxxx
Regard Kevin
