This bit is the giveaway...reason: mce: [Hardware Error]: Machine check events loggedIf you don't currently have mcelog installed then install it and run the mcelog command and see what it says. Replace custom functions, leave built in functions untouched? 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. great post to read

This is fixed with this patch To apply to a kernel: download raw patch , cd kernel source, patch -p1 < patchfile, recompile. If you are a BIOS writer or system vendor seeing this message on your system please see the page on BIOS support . I get a "only decoding architectural errors" message. What should I do?

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 Hardware Error Machine Check Events Logged Ubuntu One should also add that many platforms don't have stable CPU numbers.

Mcelog: Failed To Prefill Dimm Database From Dmi Data By default, the service runs mcelog as a daemon.

Is there such thing as a "Black Box" that decrypts internet traffic? Here is this machine check output. I inject errors, but nothing happens In many systems where EDAC is running it may intercept all errors before mcelog can see them. this content The DIMM database prefill relies on a specific non-standard format of the DIMMs in the DMI BIOS tables.
Your computer experienced a hardware error and the kernel logged an event in a buffer. Hardware Event. This Is Not A Software Error So if you see the "Machine Check Events logged" message but mcelog does not return any data, please look /var/log/mcelog.The output received may not always be easy to understand. The error could be generated even by PCIe bus. –Mircea Vutcovici May 31 at 18:05 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign
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.
You only need to worry when you have a high number of corrected errors in a short time. Please tell me what it means You have to ask your hardware vendor. If this format is not used by the BIOS mcelog will only discover DIMMs as they get their first error (iff the CPU reports DIMMs in machine check errors).

mcelog retrieves errors from /dev/mcelog, decodes them into a human readable format and prints them on the standard output or optionally into the system log. Who lost to Glass Joe? You got that notification because OSSEC found the word "error" in syslog. It consists of separate drivers for specific platforms that use hardware facilities to do memory error counting and DIMM topology discovery.
Note Some reason where there are real problems1. In this case you may need to look for the machine check data in the BIOS log. Although I don't think it is off-topic, you'll probably get more help form Unix & Linux or Server Fault. –Eric Carvalho Apr 4 '15 at 21:50 3 @bodhi.zazen All it Browse other questions tagged hardware error-handling or ask your own question.
