Error description

• Spectrum Storage, formally Tivoli Storage Manager, can
  encounter a memory leak when the following three
    conditions are met:
      1) NODE REPLICATION is running.
      2) Files being replicated are stored as fragments.
      3) Some type of error is encountered or DB Corruption
  
    This is a rare case and all three items must be met
    to see the memory leak.
