System Locks up overnight

[samsc]

is this thing still crashing - a lot - like every few hours?
or just occasionally?

we both know this is some kind of intermittent hardware failure.

its tough to debug with so many permutations of the components involved.

when i worked at V*L it always used to be the cables and connectors that failed the most - in the most difficult way to debug

Just a note on SCSI adapter cards:
The driver updates and firmware updates go hand in hand. It's not enough to check one or the other - do both.

I have upgraded the drivers and the firmware. Didnt help. Now when I get the units back i am going to start swapping components between the mached pair of machines. The server crashed after several hours of inactivity or at least activity with no DMX applied. Its an odd problem.

When did you work at VL?

Similar problem or not, I don't know actually. In my case, I took off the memories, then slotted in those.
Apple Support mentioned that is memory issue in this article.

This is for Xserve,but our G5's power light flashed three times.
Now the G5 looks fine.

apple actually ships a hardware test cd with the computers, that loads before the OS loads.

it is supposed to do memory tests and the like.

the intermittent problems we are seeing here, are not likely to be memory related.

if the memory is incorrectly installed, it just wont work at all.
