Error description

  • Server 7.1.1.000 and higher may crash at
    the end of "backup stgpool"
    process, regardless of whether the process succeeds or fails,
    if it is backing up data from a node that has the
    node attribute SPLITLARGEObjects set to "yes".
    
    
    There are no messages in activity log linked to the crash
    situation.
    
    On AIX platform, the dbx debugger will show a stack similar to:
    
    Segmentation fault in BfFreeCopyControl at 0x100985e50
    ($t304141)
    0x100985e50 (BfFreeCopyControl+0x230) 7d64302e        lwzx
    r11,r4,r6
    (dbx) where

    AfBackupPoolThread(??) at 0x100bc1bb4
    StartThread(0x0) at 0x10000cadc
    
    Another way of identifying this crash on AIX platform is to
    review the CORE_DUMP errpt -a entry, which will show BfFreeCop
    entries:
