Integrity 4640 giving a problem

[panks]

I have two HP- Integrity 4640 servers.
Today one of them hannged and was not accepting any connection. Then I looged in using MP IP and tried to take the console, but still it was not going to it. When I checked the server status LEd, so found System LED turned to orange and was blinking.
The same thing happened before few days when the second 4640 hanged and it was also giving the same indication, the only option was to to reboot.
What could be the reason !!
