All,

  I'm getting the following (flagged by FCP) in my syslog:

May  6 22:37:21 unServer kernel: mce: [Hardware Error]: Machine check events logged

They are occuring about every 1-3 days for about the last month. Is this a bad ECC DIMM? I haven't rebooted since this started, so I'll start there. Any ideas how to read this error?

 

I'm running a XeonD-1520 setup on an AsRock D1520D4I on unRAID 6.4.1. It's been in service about 20 months. 

Thanks!

Josh

Check the board's system event log, there might be more info there.

I'm not seeing any corresponding events logged there. I'm reconfiguring the log rotation in the IPMI to make sure I'm not missing anything from a full log file. After rebooting the server, I've had three recurrences of the error in two weeks. Not sure what I'm dealing with here.
