You're not alone with this problem.... Although I'm seeing it when Amanda first
goes out and does it's planner stuff with dump(8). The tape drive is located on
another system, so it's not drive related. I've also increased the timeout
values. My system lockup symptoms are also the same. Justin is working on the
problem.
