Hardware Errors - syslog messages

[dalben]

My server has the hard occasional lockup.  Replaced RAM, CPU, cables etc but it can run fine for a week, or lockup a couple of times a day.  In every instance there is never any indication on the syslog of what caused it.

 

It locked again today.  Looking at syslog I see some entries I've never started before.  it's either an unraid triggered dump/trace, or something else.  I've attached the portion here in the hope someone can translate it into english.

 

It all starts with:

Dec 18 09:53:38 tdm kernel: ------------[ cut here ]------------

 

And there's about 15ming of these entries before stopping.

Just coming back to this advice.  After uninstalling corefreq my server hasn't crashed.  Thanks.  My wife and kids now like me again.
