Hi, 

Here's a bug report we had yesterday:
The machine was completely stopped, keyboard and mouse 
were not active, we could ping the machine but no access to its files.
Only one solution: reboot the machine. We ' re looking for some 
information about this crash. Thanks a lot if you can help us.
I send you a .txt file with all the kernel information and the last 
lines in the log we had.
Thanks a lot.

Laurent.
