Alfresco works once

[alanore]

I've got a weird problem with Alfresco, it will only work once, when I reset the server it never works again. I've install various versions of Alfresco on various version of Ubuntu server, from 8.04LTS through to 9.10. Everytime it will only function once after that it gives a 404 error with a description of "The requested resource () is not avalible." Thats when I browse to http://192.168.0.254:8080/alfresco. Orginally I though I was getting something wrong, so I used the Ubuntu 9.04 GUI installer via the apt-get command, and it done the exact same thing.

The server it is installed is:
Ubunut desktop 9.04 32bit
AMD 64 dualcore 3800+
512MB of RAM
and SATA disks

The only error showing in the alfresco log is

ERROR [org.springframework.web.context.ContextLoader] Context initialization failed

Does anyone know why this keeps occuring?

So you install Alfresco, run it, and whenever you restart your server, it shows the same error message in your log?
Does Alfresco load automatically via an init script?
Do you simply unplug the server (what exactly happens during your "reset")?
The message says, you're not having a WebScript folder anymore - but since it originally worked, this could only be a manual delete or a data corruption (is it always the same message?).
Since Alfresco doesn't find the folder, it cannot start up (context initialization failed), hence you get the 404 error message.
What is irritating, though, is the message saying
Registered 24 Web Scripts (+0 failed)
at the end - while it says that there is no webscript folder to be found.
