Hello,

There are some APARs that describe deadlock during expire inventory :

 ERROR DESCRIPTION:
 Deadlock situation during expiration may occur when processing
 archive objects of converted nodes. If the DeleteFilesThread

 deletes a batch of files it holds a xlock on the according
 filespace. This prevents the ExpirationSearchThread from
 obtaining a slock on that filesspace to report it's position.
 While it has to wait to get the slock granted it holds an islock
  on the according node id. If now, the DeleteFilesThread processe
 s an archive object of a converted node it want to get a xlock
 on this node id which results in a deadlock.

If you are running ADSM in AIX, the apar number is IY05562
and the solution is to apply U468795 (service level 3.1.2.50)
