What do you make of the following in the event log of the second dual xeon server I just had setup?

I think it you need to submit a ticket...

(I know you know that as an obvious answer, but decided to say it anyways).

Be ready for them to have your server for awhile. One of my previous P4 servers had some issues and it was "under tests" for about 27 hours (unavailable).
I know how bad it feels when you are excited to bring a new server into your fleet and it has something wrong with it (after you spend days getting it setup).

See if you can get the Dell OpenManage tools installed to run a diag from Windows.

Thanks for the reply,

OK, submitted a ticket.

Better to find out early on than later on I suppose.

It's a linux server... will do some reading on the openmanage tools for linux.

Agreed.
Even if they don't find anything, ask them why you are receiving such errors because there should not be a reason.
The tech's are there for hardware so better to do it now than have it go offline and loose customers data.

I ran memtester overnight and it generated around 100 more errors in the event log matching the above.

Tech support volunteered to replace the RAM in the ticket.

That memtest probably sped things up.
Glad they were willing to agree to a replacement quickly.

Jeff

Dec 15 2007, 10:32 PM

Memory swapped. Running a final memtester now just to be sure.

The memory fault was a hurdle I didn't expect when setting up this server, but I have to say I was very impressed with tech support's direct and on-target support to resolve the issue quickly and efficiently.

So what were the results of the memory test? did the RAM swap resolve it?

Jeff

Dec 16 2007, 05:49 PM

Yes, ram swap resolved it.
And no more bad entries in the system's event log.
