today in the morning a server hangs, running SLES11 Sp2 on VMWare 5.1 .
It was not posible to login via SSH but ping works.
Then i tryed to login via VMWare Console as root.
So i wrote "root" at the login prompt but i cant write the password... the session hangs after pressing "Enter / Return".
The logs dosent show anything. In the VI Client i saw the VMWare tools are not running.
So I reset the server and now everything works fine again
I was have that problem about 5 times this year on different Servers.
