Dump files suddenly grew "exponentially"

SVN Version: 1.8.8 (part of a Collabnet 4.0.5 install)
OS: RHEL 5.10

So today I just got an alert that my disk space for dumps ran out. The
dumps typically take about 2.4 gigs of space uncompressed. I noticed
yesterdays suddenly went to 4 gigs.

And now, it hits about 40 gigs before I run out of diskspace.

When I do a "du -sh reponame" I see what I would expect, the disk
usage of the repository is still only about 2 gigs.

I'm just running "svnadmin dump reponame" by hand now. If I leave off
quiet, I see it rapidly spin through "Dumped revision 12345" message,
and than wham... it updating revision ... and starts to chew up disk
space at around 2 gigs, and contines on until it fills up disk space,
never reporting another revision number being dumped.

The revision number it is stopping on is not the most recent one, it
looks like it was probably from about 2 days ago, when this started.

Anyone have an idea of what is going on here?
