Error description

• The IBM Spectrum Protect Client sessions may hang or timeout, if
  deduplication statistics is being generated at the time on the
  IBM Spectrum Protect Server. The servermon script collection,
  with enabled process stack dump, will show threads waiting in
  AdmLockNode(), SHOW RESQ will show many node sessions waiting on
   locks, and SHOW TXNT will contain a transaction with a held
  DEDUPSTATS lock along with a transaction with held locks for the
   same node names as seen in SHOW RESQ output.
  
  IBM Spectrum Protect Versions Affected:
  IBM Spectrum Protect Server 7.1.3 and higher on all platforms
  
  Initial Impact:
  Medium
  
  Additional Keywords:
  Spectrum Protect; TSM; client; connection; session hang; session
  timeout; ANS1695E; dedupstats; AdmLockNode
  

Local fix

• 1) Run the processing against the nodes individually with
  separate commands
  2) Schedule it to run when the client is not connected to the
  server
