Rollback too small... on analyze???

Oracle 8.1.7.4 on HP-UX.
I've got a client trying to insert into large tables in batches of
5 million rows which is taking about 20 minutes per 5 million. No
problem there.
The problem seems to be that he runs an analyze compute statistics
afterwards and about 1 out of 5 times he gets a rollback segment
too small. I wouldn't think analyze uses rollback.. It happens
so infrequently and ALWAYS seems to work if they simply run it
again.
What I suspect, though have no way to prove, is that the rollbacks
are still dumping out after the last batch of inserts and the
analyze gets a bit confused on this.
I have suggested they put a 3-5 minute "wait" before they run
the analyze and see if that clears the problem up.
Is there any firm foundation to this?
What might be cause this?
The only other process running at the time was another insert
batch on a different table.
