Error description

  • Tivoli Storage Manager v6.2 server may run out of memory due to
    memory leak when a transaction is aborted and resent by the TSM
    client deduplication session (see client dedup APAR IC69038)
    
    The system memory is used up by the DB2 db2sysc process and
    causes the system to crash.
