APAR status

  • Closed as program error.

Error description

  • When a set statement that references row variables is executed,
    you may find a memory leak in the application heap in DPF.
    
    You can monitor the growing memory usage in an application heap
    in DPF by running:
    
    db2pd -db <DBNAME> -memblocks appl -alldbpartitionums
    
    Note* The above reports only information from database partition
    servers on the same physical machine that db2pd is being run on.
    
    After running the command for this scenario, you may find
    something similar to the following in the output:
    
    PoolID  PoolName   TotalSize(Bytes)     TotalCount     LOC
    File
    1          apph          3                           3
    5833   930532034
    

Local fix

  • Terminate the client connection to free the memory heap
