It's obviously this I/O error that's causing the problem... the
filesystem is 67 gig (df -k says 67108864 1048-K blocks). The other
filesystems being backed up to the tape only are using 3-4% of tape
capacity... and it's a DLT 40/80. The compression ratio seems like all
this should fit on 1 tape:

but maybe it's possible this 67-gig filesystem is filling my DLT tape
up, it reaches the end of the tape, and it I/O errors? If so I need to
do some math (blech) to determine how much data we can get rid of on
this big filesystem...

A little further in the NOTES section of the amanda report,
you can find out where/if Amanda hit into EndOfTape.
Here is a snippet of mine:

NOTES:
taper: tape ARCHIVE-032 kb 33920672 fm 14 writing file: No space left on device

It says that while writing file nr 14 it bumped into end of tape after
writing almost 34 GByte to that tape. (The file is taped again completely on the next tape.)

What does your report indicate? Is it what you expect for that tape capacity?
