Hmmm. Under 15,000 - you might still be bumping into the FID limit. Try using Mark's player patch for adjusting the maximum FID count.

Additional: Also, if your player is that extremely full, you might be running into trouble where there is not enough space to rebuild the database files. Neat trick, but I know that there are strange things that happen when you completely (and I mean completely) fill the drives. You may need to even clean off a bit of space manually until you can get to a point where you can work on it with emplode or jemplode.
