Processor heated above trip temperature. Throttling enabled.

I have an issue with 20x ProLiant DL380p Gen8 servers. These servers are part of HP Vertica cluster. All servers are running on power performance mode.
OS: CentOS release 6.6 (Final), kernel  2.6.32-504.8.1.el6.x86_64 

there are a lot of messages in /var/log/mcelog and dmesg:

CPU27: Package temperature above threshold, cpu clock throttled (total events = 86472)
CPU15: Package temperature above threshold, cpu clock throttled (total events = 86471)
CPU14: Package temperature above threshold, cpu clock throttled (total events = 86472)
CPU28: Package temperature above threshold, cpu clock throttled (total events = 86472)
CPU24: Package temperature above threshold, cpu clock throttled (total events = 86472)

It looks like mcelog bug according to https://bugzilla.redhat.com/show_bug.cgi?id=924570

Anyone facing same issue? Can you recommend how to resolve it?

Re: Processor heated above trip temperature. Throttling enabled.

That BZ looks to be geared more towards laptops.

What kind of load are you running on these systems. If it is very heavy CPU / memory intensive you can hit the CPU internal temp trigger before the system can react and ramp up the fans which will result in the MCE entry. Try setting the fans to 'Increased Cooling' and see if the errros stop. Increased Cooling will usually resolve the issue. If you still see the error try 'Maximim Cooling'
