Running of space(WUICKLY) in /usr/openv/netbackup/db/images/

Hello folk's
I have a master (sol2.6) running NBU 3.2 patch J0820443,
I have a situation were the images dir is growing VERY fast,
it appears to be acting like Netbackup did a few years ago,
the images directory would just grow untill it ran out of
drives spaces to hold them, tech support never got back to me then,(OpenVision
TS)
Any clue as to what could be causing this behaviour?
New patches?
(i realize that i am not giving a lot's of info here)

How quickly is quickly? And how big?

This DB is going to grow very fast up to several hundred MB for even
small
setups because it is a DB full of "holey" data. If you have a lot of
files it gets
even bigger. For example, I have one NFS server that has about 50 GB of
space,
and takes up 750 MB in the database steady-state, with only a two-week
retention period.
