I recall a while ago I had an unbalanced set of DLEs.  A couple quite
large, relative to my daily "average" and a high percentage of a single
tape, and a number of very small DLEs.  Each of the large DLEs seemed
to get its level 0 on the same day every dumpcycle.  On the days there
was no large level 0 to do, amanda seemed to fill in with lots of small
level 0s.  This caused it to do level 0s multiple times during a dumpcycle
for the small DLEs.  Maybe you are seeing the same behavior?
