I get "machine check events logged"? In this case you may need to look for the machine check data in the BIOS log. When a corrected or recovered error happens the x86 kernel writes a record describing the MCE into a internal ring buffer available through the /dev/mcelog device. From mcelog manpage: X86 CPUs report errors detected by the CPU as machine check events (MCEs).
They can change between boots. Old Linux kernels reported the CPU APIC ID instead of the Linux visible CPU number. On a cluster of systems the low rate of all the systems combined may actually be a high rate on a central logging server. Mca: Memory Controller Gen_channelunspecified_err It consists of separate drivers for specific platforms that use hardware facilities to do memory error counting and DIMM topology discovery.
I inject errors, but nothing happens How do I get an overview of what errors happened on the system? This is not a software error.

There's unfortunately no fool proof way for mcelog to detect it. /proc/cpuinfo has a field for APIC IDs so it's possible to translate them back manually. Mcelog: Failed To Prefill Dimm Database From Dmi Data Changing file permissions given its symbolic link Program template for printing *any* string Idiom for situation where you can either gain a lot or lose a lot Why don't quaternions contradict probably some good reason, maybe –Xen2050 Apr 10 at 23:04 1 @Xen2050 Because the decoding of the message is architecture dependent and it is not always documented by hardware manufacturers.

It won't be able to decode model specific errors, but it will log them all in a raw (hex) format. http://www.advancedclustering.com/act-kb/what-are-machine-check-exceptions-or-mce/ Most errors can be corrected by the CPU by internal error correction mechanisms. Hardware Error Machine Check Events Logged Centos That is what mcelog is trying to do. Mca: Internal Parity Error I get "Cannot open /dev/mem for DMI decoding" I get "failed to prefill DIMM database from DMI data" How do I enable corrected memory error reporting on Intel Xeon 7500,6500,E7 series
In fact, the only thing that differs from the cited post is the time stamp. this contact form CentOS 5 dies in March 2017 - migrate soon!Full time Geek, part time moderator. The DIMM database prefill relies on a specific nonstandard format of the DIMMs in the DMI BIOS tables. Most errors can be corrected by the CPU by internal error correction mechanisms. Hardware Error Machine Check Events Logged Suse
How do I "run through mcelog --ascii"? Also over a long uptime the total number of corrected errors may also be quite high. And the customer would like to know if the detail information is always recorded to /var/log/mcelog when the above message is logged in /var/log/messages. http://indowebglobal.com/hardware-error/hardware-error-221.html xx xx xx:xx:xx xxxx kernel: [Hardware Error]: Machine check events logged We know that this message is harmless under the customer's hardware environment.
mcelog is on a rolling release through the git tree. Hardware Event. This Is Not A Software Error This indicates that one of your memory modules has failed. I inject errors, but nothing happens In many systems where EDAC is running it may intercept all errors before mcelog can see them.
A small number of corrected errors is usually not a cause for worry, but a large number can indicate future failure. What danger/code violation is oversized breakers? Here is this machine check output. http://indowebglobal.com/hardware-error/hardware-error-148.html But it is harmless message, so customer will ignore the above message and check /var/log/mcelog instead.
This likely indicates some problem. mcelog ships with a daemon capable mcelog, but the init script is disabled by default. How to sample points randomly below a curve? DIMM failureBelow is an example of DIMM failure reported in mcelog Hardware event.

The important errors are usually architectural, but sometimes new architectural errors are added, and you may not see them decoded. How do I enable memory error reporting on SLES11-SP1?
