Hello,

maybe someone can help us. We are running a Mail-Server in a xenU-Domain since 3 month without any problems.

But now we have trouble with dom0. In dom0 the ssh-Daemon is running but we only can only login sometimes via putty (Network error: Connection timeout).

We need 5-8 times till we can login with putty. After login the server is very very slow. Processes respond with delay.

Does someone have an idea?

Thanks,

jansen

Here some infos about the server:
