That seems to have helped a lot. Amanda finally backed up again the
same DLE that brought up the issue. Unfortunately, I set the value to
1 Gb, and got two splits, 1.7G and 3.0G.

Sorry, but even after reading your remarks above and experimenting
with it, this writeup is still obtuse. For one thing, I had no idea I
was splitting in memory. Isn't that normally done on the holding disk?
