Error description

  • Domino Memory leaks regarding to: 0x8252    BLK_NSF_POOL and
    0x834a   BLK_GB_CACHE
    
     leading/contributing eventually to Domino crash .

    [1920:0002-1E1C] [12]: 607F3C25 NSFApplyFolderReplOps
    
    The leak is in the normal processing for this code.
    
    
    NSFApplyFolderReplOps will delete the EHDIR block that is
    leaking if
    there are a small number of updates and all the entries fit in
    the first
    block of folder operations passed.
    
    If there are a lot of folder ops it saves the EHDIR block to use
    with
    each block of folder ops that need to be processed. When the
    EHDIR block
    is closed the bit that it uses to determine if it should be
    freed is off
    and it's leaked.
    
    
    
    The leak is very small. There are 1429 + 1085 blocks between the
    two
    call stacks. The blocks are 32 bytes long plus the overhead in
    the
    bpool, which uses 64 bytes each. So a total of 160896 bytes have
    been
    leaked."
