DL380 G3 "memory parity error" problems

My company has a good amount of the DL380 G3 servers deployed throughout the world in support of our work. There is an increaed trend starting to show with a particular error. In the last 60 days, I have had 12 cases opened for an error that cause a blue screen of death stating "Hardware Malfunction error NMI Parity Check Memory. Please contact hardware vendor."

I can reset the server and have it come up and without warning within one hour to a couple days, it will happen again. Each time I call HP for support, they will never tell me whats wrong and their fix is to just send a new motherboard out.

Could someone tell me if they are experiencing the same problems or know what might me causing this. We are running NT4.0 and the only add-in card is a 64-bit PCI-X dual channel SCSI card. Thank you.

With other proliant is was an issue with PCI cards - netflex network cards in particular.

Check you have the latest firmware/drivers installed.

Re: DL380 G3 "memory parity error" problems

Yes, everything is up to date and current. All drivers, firmware, software versions, other than NT that is. Using the built in Gigabit NIC on the server. Only add in card is the SCSI one as stated earlier.

Don't know if this is any use as it's old info regarding a 1600 but I believe it is a PCI problem.

Unfortuantly I have never had this problem on a modern server.

Re: DL380 G3 "memory parity error" problems

Miles, try to disable HT (Hyper Treating) from BIOS, also please check what option you have from BIOS in the memory Protection mode, I don't recall exactly if there any option to disable Parity check, I do assume System ROM is Up to date, and latest system management Driver loaded for NT4. Also is there any chance on the one of the NT4 servers to reload with 2000 and monitor Server. DO you have any box loaded with 2000 or 2003 with same HW configuration where no Problem ever occurred?

Here is more about NMI

Is all installed memory original, not mixed by ASSY part number?

Is any server continue do so after System Board Replaced ?

Re: DL380 G3 "memory parity error" problems

Hi,

I've not seen this problem on any of our DL380 G3s however I've had one BL20pG2 do it quite regularly.

My fix for this particular server was to swap the memory.

That said, if HP are insisting on swapping out the motherboards rather than the memory, that implies that they're aware of a problem with that particular board. They're not going to go to the expense of replacing a motherboard if the problem could be fixed by swapping memory.

I take it that the machines with the replacement boards work OK...

Cheers,

Rob

Miles Ashley, Let me know if you have anything more from HP on this error you described. Anything is helpful. If they do not fix this right away, we are going to dump several multi- million dollar contracts with them this year.

Re: DL380 G3 "memory parity error" problems

No, I have heard nothing from them regarding this matter and it keeps occuring more and more. We are still averaging one server every five days having this error. There answer is to always to just swap out the motherboard and give us no indication as to what the error is. I am getting very fustrated with the lack of support on their end as well. I have tried replacing various parts, disabling HT and none of this seems to work.

They have a similar issue with the SCSI backplanes going bad to giving indication that the hard drives have failed. There is a customer advisory related to this:

I am very disappointed in HP's service and support in regards to these matters and can not recommend them to anyone because of this.

We have matched this error with this event.

Abnormal Program Termination (BugCheck, STOP: 0xC0000244 (0xC0000001, 0x00000000, 0x00000000, 0x00000000))

Please check the following microsoft article.

232564 STOP 0xC0000244 when security log full
http://support.microsoft.com/?id=232564


We are following up with Microsoft regarding this error and the crash event. I will post any update when i recieve one.

Re: DL380 G3 "memory parity error" problems

You mentioned you were using NT 4.0, do you have any 2000 servers with the same problem? There are a lot of patches for 2000 I know (related\unrelated) but it appears those have not solved it, according to many other threads with similar or the same exact issue.

Re: DL380 G3 "memory parity error" problems

Ok I'm back and we have this issue all resolved. We are running Windows 2003 servers.

This problem relates to not being able to write to the security log, even if your log file is under the specified limits according to documentation.

If you have a stop error of this sort a flag will set in the registry on your server this can be found at HKLM\system\currentcontrolset\control\lsa the flag name is crashonauditfail if this is set to the value of 2 then you are running in an unsupported state. This setting is set to 2 to allow an administrator to log on and clear the security event log and restart the server (which sets it back to the value of 1).

We have found the policy setting which causes this and have turned it off. This setting can be found in computer configuration\windows settings\security settings\local policies\security options
audit: shut down system immediately if unable to log security events. we set ours to disabled.

We are no longer getting the stop errors, and we are finding that our servers frs service is communicating correctly (a by product of our original problem).

I hope this helps..

Regards
Stephen

Re: DL380 G3 "memory parity error" problems

Stephen, Do you have the same exact servers (though you are running 2003 and we are not)? And are you coming up with the same exact memory parity errors as we are? or something else (a possibly mismatched error code?)?

Re: DL380 G3 "memory parity error" problems

That actually helps me out none. I'm running NT4.0 and getting the "memory parity error". It has nothing to do with a security log or a security audit. That error has never occured.

Re: DL380 G3 "memory parity error" problems

That security log problem is something totally different with us too. Not the same problem at all. We are still getting the parity error on our servers. HP is replacing the motherboard (temporary relief) and we are replacing the RAM chips (brand new) on our own, which so far has given us the greatest relief.

Re: DL380 G3 "memory parity error" problems

I've tried replacing the RAM chips and that didn't seem to have any affect. When we get a new mobo in from HP, we still use the same RAM from the old mobo and haven't had the issue come back.

I spoke with a Regional VP from HP on Tuesday regarding this matter. He wanted me to get him every serial number for every G3 server my company uses and then HP would look over the S/N to see what boards were affected and issue new ones. Since we have the servers all over the world, this is not an option and would take entirely too long. I asked if he could just get us a lot of 25 mobo to keep around when it happens and then send the bad one to them and he didn't want to do that. HP customer service at their finest. I'll keep you informed when I talk with them.
