Hello,

When I start up amanda my load (which normally is very low) starts to climb.
I'm on RH Linux 8.0 dual xeon processor, 2 gig of memory.  SCSI tape, raid array
on different channels... this high load continues for about 9-10 minutes
then it drops down to a load average of around 1.5.

Nothing else is going on on this machine.

This is fine on a couple of my machines, but the one that I can't run this on b/c of this bogging down of the
machine.  Is there anyway to adjust settings so it doesn't do this?

I really don't care if it take a bit longer to run if it doesn't kill the machine....

Here is the output from the last run:
