New Proxmox Server MCE Hardware errors

[Nox71]

HI all, last week i have build a new Proxmox server from a Lenovo Thinkstation P710 with two Intel Xeon E5-2620 V4 with 192 GB of DDR4 ECC memory. I have created all my VMs on it and everything is working fine except for one thing i am getting those erros in the Syslog every minutes:

May 01 08:27:53 srv-pve kernel: mce_notify_irq: 59 callbacks suppressed
May 01 08:27:53 srv-pve kernel: mce: [Hardware Error]: Machine check events logged
May 01 08:27:54 srv-pve kernel: mce: [Hardware Error]: Machine check events logged
May 01 08:28:54 srv-pve kernel: mce_notify_irq: 59 callbacks suppressed
May 01 08:28:54 srv-pve kernel: mce: [Hardware Error]: Machine check events logged
May 01 08:28:55 srv-pve kernel: mce: [Hardware Error]: Machine check events logged

My server is not crashing and all the VMs are working fine but these errors are worrying me.

Any advice on that ?

Thansk in advance for your help!

Have you looked at the mcelog in /var/log? What about your SEL or other logs in your management controller.

This is all the log i have in /var/log so i don't know which to look:

Okay, so no mcelog is installed ... what yout your SEL?

Hi,

any update in this topic ?
I am struggling similar issue but with different interval.

as I already know... MCElog is not installed anymore... I installed RASDAEMON but same result... no info what is wrong....
some people says that rasdaemon have some bugs.. some people says... any UEFI/BIOS MCE handling is somehow on... noone knows...
https://github.com/mchehab/rasdaemon/issues/95

other proxmox topics... also without result :

https://forum.proxmox.com/threads/hardware-errors-at-regular-intervals.127228/

 

[LnxBil]

what yout your SEL?

still no answer to my question.

if You are asking me ? I have two different HW and both without 'issue'
one :

[LnxBil]

I have two different HW and both without 'issue'

Good, but bad for the post.

Updated BIOS? Sometimes it's just like this. I have also a machine with check exceptions and the vendor analysed it, no problem. Besides the MCEs, there is no obvious problem, so we now just ignore it.

 

[Szymons]

On QANTA server mce error log dissapear after replacing Fibre Chanal card.

Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02)

But still PROXMOX team... why there is no info what is that 'hardware error'... MCELOG not exist anymore , rasdaemon not working well...

On supermicro problem persist...

Also seeing this issue. I can increase the frequency of these errors when stress testing the VMs but have had 0 issues with stability on any VM. First found this issue in my Gigabyte BMC (see attached screenshot) and this lead me down the rabbit hole of installed rasdaemon and checking for ECC error via ras-mc-ctl --error-count but that shows 0 issues. I've been trying to find a solution to this issues for weeks now but have come up with nothing and I'm about to just say "I hope this doesn't become an issue down the line" as I've seen no performance impact yet. Any help would be greatly appreciated

I'm dealing with a similar issue. Not sure what to do, memory tests pass, the bios is already up-to-date. Some people are saying this is hardware failure, but I'm skeptical...

Maybe its a CPU driver bug with the current kernel in use..?

I ended up buying new RAM that was on the Gigabyte QVL (Qualified Vendor List) and this fixed my issues. I realize this isn't a great solution but I think that (just like all AMD processors) the memory controller is super finicky so staying as close to recommended spec is almost a must. I am re-selling the 8 32GB DIMMS I have as I don't think they are faulty but took this time to double my memory from 256GB to 512GB as I found a good deal

 

[aoiblue775]

That could be it for us as well (only, its weird because the memory test didn't catch it)... Maybe we'll try this if RMA-ing the CPU doesn't do anything.

 

[LnxBil]

I don't think it would. The MCEs I encountered did not yield a problem in the OS, it just created a lot of MCEs that spam the log and will degrade the memory performance due to the fixes that were detected, corrected and logged. Unless it'll be consecutive errors at some point.
