I did check the dtimeout value.  It was set to 3600, which seemed like it
should be enough.  I'll increase it to 7200 and see what happens.

If the dump is timing out, shouldn't amanda properly kill the processes
though?

I've read about the advantages of software compression over
hardware compression and I agree.  I'm not the primary amanda
administrator - I'm just filling in while he's gone and attempting to
fix the problems - but I will make the recommendation to switch.

Will the using hardware compression cause the dumps to take longer?
We recently switched to hardware compression because we got a new tape
changer.  Perhaps that's the cause of the problems.  These 2 machines
were not having problems previously when we were doing software
compression for everything.

Thank you for your recommendations - I appreciate it.
