I have a similar one.  It's 4.5M objects with odd retention.  Everything before 
and after it in the expiration process completes in my 12 hour window.  It 
takes 2+ days.  When I see expiration hung, I cancel and restart without 
specifying duration.  It's a weekly procedure for me.

Subject: [ADSM-L] SV: Expire Inventory Hangs?

Hi,
Their is no backup or restore session active.
And the Expire inventory can hangs for over 24 hours without any problem on the 
same node and on the same filespace. So I,m guessing it is a corruption in the 
TSM Database.

Does the client have a session open with the server while you're running EXPIRE 
INVENTORY? (That probably was one of the first things you checked, but you 
didn't say so, so I ask. :-) )
