IT32044: MEMORY LEAK IN CLIENT SCHEDULER WHEN DOING SYSTEMSTATE BACKUP

APAR status

• Closed as program error.

Error description

• The dsmcsvc.exe process is using more and more memory after each
  scheduled backup if it is doing systemstate backup.
  That problem  is not seen when using the client acceptor
  scheduler as the dsmcsvc is closed after each backup finish.
  
  Spectrum Protect Versions Affected: All V7.1 and V8.1 client on
      Windows platforms
  
  Customer/Support Diagnostics:
    From Windows task manager, find the dsmcsvc.exe and look at
    the column "Memory (private working set)" .
    That value may increase by a few MBs between each systemstate
    backup.
    That check must only be done when there are no backup ongoing,
    because it is normal to see higher value here when backup is
    ongoing.
  
  
  Initial Impact: Low
  
  Additional Keywords: cad , TS002897779  , sched  dsmc ,
    managedservice
  

Local fix

• . Use the client acceptor scheduler instead of the standard
    client scheduler.
  or
  . Restart the scheduler service from time to time to clean
    memory.
