Re: high load but idle CPU



Do a ps -ax and see how many processes you have stuck in D state ;). Then
go and get 2.2.9

Also, load average does not relate to how hard the CPU is working and CPU
use has no bearing on load average. The load average is the average number
of processes that were waiting to run over the time period. Also, you can
have a process eating 100% of cpu and if it is at very low priority (the
distributed-net clients come to mind) your system will still be very
responsive.
