Here's a good one....



I have a sparc 1+, 64 mb ram, Quantum Pro 1.2g, 2 seagate 9 gig ccd'd, and
a Mamouth-LT (14 gig native 8mm) configured for a file server.

My problem is I am experiancing some stalls in performing a 'dump' command.
Now, it's important to note that the system does not hang, just dump.

Here is a snip from the message log........

Notice the esp errors above. What do they really mean? Is it related to my
backup? Is this just a tape driver issue for my Mamouth-LT drive?

Note: The exact configuration (minus sparc) worked fine on my FreeBSD 4.X
box, before it got retired.
