IC74922: AE IC64921 FIX COMPLETION

APAR status

• Closed as program error.

Error description

• When issuing a 'DELETE FILESPACE' command for a filespace that
  contains data in a deduplicaion storage pool and includes a high
  number of very large files, the TSM server may exhibit a high
  amount of memory utilization.  Under these conditions, the
  'DELETE FILESPACE' process performance is severely degraded  as
  well potential memory paging issues that could cause further
  issues.  This is caused by areas of the dedupe processing that
  make calls for an in-memory list that is built during deletion
  processing.  At end transaction this list is added to a table
  that is then subsequently deleted by other backend server
  threads.  The current group size used for transaction in this
  processing can become prohibitive under the conditions.
