Upgrade Causes 30% more data?

[Mark]

Hi all

My customer upgraded ADSM 3.1 to TSM 4.1. Since the upgrade he has a number of 
problems which I believe could all be interelated. 

The symptoms are as follows:

1. 30% more data.
2. Less expiration going on.
3. Running out of scratch tapes
4. Reclamation used to free up scratch tape but this seems to be happening less 
frequently.

Any ideas folks?
