Perfectly working appliance (web, ssh)

Now one day I decided to just stop working as it should

SSH presents user name/password prompts, but inputing password makes it hang
there for minutes before returing prompt

Console does not present login (it is by default X GUI), just the turning

init 3 as defaultgives all sorts of errors

Restarting all Zen services by hand takes ~ 20 minutes (10 min to stop & 10
min to start them)

Anybody any ideas how to tackle it?

Appliance does not use excessive memory or CPU (but plenty of resources
