Hi Centos Users
The server (ProLiant DL380 G5, Centos 4.3) was not responsible anymore
(SSH), fans rotated at full power and the console was blank. After
restart it seems to be fine.
Now I am analyzing sar statistics (in system logs nothing special,
unusual). The hardware monitoring with HP tools didn't work.

How its possible that the total CPU is 90% busy, but CPU 1 + 2 only
1%? The server have 2 processors.
