Sounds like the kind of thing that would happen if the file
had a lot of overflow.
Or a very badly designed index, or trigger.
Any of those possible?

We don't have any triggers on those files. There are no indexes on one of
the files and the other one has 5
Okay, tested the process against the file with no indexes. It ran in 19
minutes. it was taking hours before. I didn't save a copy of LIST.INDEX
FILE ALL DETAIL but it did have some very skewed groups, as I watched it
scroll by. But mostly it looked very even... I've never seen this behavior
I've seen this kind of thing when an index of a sparsely populated field
was created without the NO.NULLS option.

That's what I would have thought, too. However, I'm seeing this on files
that have recently been resized to about 10% larger than current need for
growth. AND they aren't that big. 30,000 items
Could they be hashing very badly?

Definitely looks like overflow - what does an ANALYZE.FILE tell you? ---
also what is the physical file structure (O.S level files and sizes).
One other possibility - is there a horrendously large indexed entry (like
10's of K multivalues or similar) ? - let's take a look at LIST.INDEX ALL
