And I am getting loads of these sorts of notifications saying that there is a Hardware Error and something about mce: OSSEC HIDS Notification. 2015 Apr 04 20:09:22 Received From: Bath-Towel->/var/log/syslog Rule: 1002 fired (level 2) -> "Unknown problem somewhere in the system."

What does mce stand for? And is this apparent hardware error anything that I should worry about?

The mcelog daemon accounts memory and some other errors errors in various ways. mcelog --client can be used to query a running daemon. The daemon can also execute triggers when configurable error thresholds are exceeded. This is used to implement a range http://www.mcelog.org/ of automatic predictive failure analysis algorithms: including bad page offlining and automatic cache error handling. User defined actions can be also configured. All errors are logged to /var/log/mcelog or syslog or the journal. For memory errors it supports modern x86 systems with integrated memory controllers; for CPU errors all modern x86 systems are supported. Traditionally mcelog was run as a cronjob, but this usage is deprecated now. The modern way to run it is to start it at boot up time and run it always as a daemon. In addition it can be used to decode fatal machine checks on the command line (but this is also usually not needed anymore on modern kernels which log those after reboot automatically) For installation information and how to set up a mcelog package (if you're a distributor) please see the README.

Wed, 12/09/2015 - 16:04 Hello, I have a custom board(RC10), which has E3845 and is similar to MinnowBoard MAX. I have customized from Intel Firmware hardware error Engine MinnowBoard MAX firmware to RC10 by enabling i2c-0, PCIe-2, etc. When the Linux system boots, it shows "mce: [Hardware Error]: Machine check events logged" 300 seconds after the boot. 1. Since the original configuration came from the MinnowBoard MAX, which uses E3825, the mce error might come from it. If yes, how can machine check events I change the processor to E3845. 2. Other than #1 I don't have any idea where the mce error came from. Is there any way to track it down by disabling HW components(e.g. PCIE-0)?

Log in to post comments Brian Richardson (Intel) Thu, 12/10/2015 - 11:22 We'd like to get the log of the machine check exception to figure out what's going on. On Linux systems, you should be able to get this using mcelog - http://mcelog.org/ As an example you can install this on Ubuntu/Debian using apt-get: sudo apt-get install mcelog The events will be logged to /var/log/mcelog. You can also run: sudo mcelog --client to query the mcelog daemon for errors. -- Brian Richardson -- @intel_brian Top Log in to post comments JONG L.

I've been seeing kernel "[Hardware Error]: Machine check events logged" messages in /var/log/messages. These seem to be from the mcelog daemon, and the corresponding logs (I posted an example below) are in /var/log/mcelog. - is a RAM chip on its way out? Or is this the CPU or CPU cache thats having issues? - if RAM, how do I determine which chip(s) are having issues? /var/log/mcelog: Hardware event. This is not a software error.

Thanks, J jmozdzen23-Apr-2012, 15:27Hi J, sounds like a RAM chip giving up... have you had a look at the SEL? Maybe that can give you more details, as the system behind it ought to know about the hardware layout of your machine... Regards, Jens ashbyj24-Apr-2012, 11:50Hi Jens, Thanks for the reply. In the System event log, I see several of these messages that occur during boot: ID = 6eb : 04/22/2012 : 00:27:29 : Memory : BIOS : Configuration Error Is it possible that there is a strange setting in BIOS that would not play well with mcelog? The machine in question is a Sun Fire x4140. Either way, we plan on taking the server down one evening and running memtest86 overnight.
