Two suggestions:
1. run vmstat 2 30
to see how many context switches are occurring and the wait time for
processes etc. A load time of 11 means there are a large number of
processes waiting for cpu time. I think it is inaccurate to say no cpu
resources are being used.
Output here:
# vmstat 2 30
procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------

Do you see anything in the above output? Load ave was 11.45 when I
started....
2. If you can get a hold of the article on the Real Time Scheduler found
in the August 2009 issue of Linux Journal. To me astropulse is running
away with your CPU time and noting else can get cpu adequate cpu time.
But its only July 2009!   B^)

I'm no longer an LJ subscriber, so I'll have to either find/buy the issue, or wait a while for it to become available on their WWW site.
Thanks Aaron!
