Could be most anything, but, you might start investigating with

$ analyze/crash sys$system:sysdump.dmp
SDA> clue crash
SDA> exit

If you've got valid crash dump and the timestamp within is recent, post the output here.

The content of the system error log might also be interesting - perhaps you've got DECevent installed? If so, the following might reveal something interesting.

$ DIAGNOSE/EXCLUDE=(CONT,VOLU)/SINC=20-JUN-2008

Sayed,

The first question is: Why?

Is there a hardware problem? Power Problem? Software Crash?

When this answer is determined, then it is possible to isolate the specific problem.

Jim,
I'll start analyze the problem tonight, I'll post the answer
Robert
i have already changed both power supplies,
tonight i am going to change both CPU's

[Robert Gezelter]

Sayed,

Personally, without error logs showing a CPU problem, I would not change the hardware.

Most hardware problems produce entries in the error logs.

Power supply problems can produce strange problems however.

Before troubleshooting the 4100, is there something else on the same power/ups that indicates a restart or continuous service?

That said, check for a crash dump and review error logs as previously noted.

Good luck,

Andy

How about posting the entire output of "SDA> CLUE CRASH" as an attachment for a start? That little snippet isn't enough to determine anything...
