Above mentioned process are causing the load..(This server does not have any application, just OS only.)


Any help will be much appreciated..




Some help from Hiro:




What version of hpvsa does your customer use?

The latest driver may solve the issue.


Advisory: HP ProLiant Gen8 Servers: HP Dynamic Smart Array B120i/B320i Controllers - HP Dynamic Smart Array Controller Driver (hpvsa) Versions 1.2.4-3 and 1.2.4-4 May Cause High Load Averages and CPU Utilization Under Linux


Hope this helps.
