samba - Sep 2009 - Upgrade from 3.0.31 to 3.3.7 now has incredibly large printer tdb files

Sorry for the cross-post, but curious if this is a known issue.

After upgrading our printer server from 3.0.31 to 3.3.7, the tdb files 
for the specific queues are growing out of control with old job data in 
the tdb file. In addition the queue from the windows view can show 
hundreds of old jobs that have long since printed.

How can we:

a) reduce the tdb file size and
b) stop samba from recording this info in the first place (as no one 
really cares from the windows side as long as their job prints :-) :-) )

Setting lpq cache = 0 was no help and max reported print jobs does not 
help either.


Cheers,
Bill
