    consume 100% CPU.
    
    Customer/L2 Diagnostics:
    A Tivoli Storage Manager server DEDUP trace will show the loop
    occurring on one or more bitfile. The series of messages that
    repeat are as follows :
    
    <timestamp> [nn][bfdedup.c][6950][BfDedupVolumeThread]:
     Processing bitfile xxx, segment 0, size 2200.
    <timestamp> [nn][bfdedup.c][1637][BfAnalyzeBitfile]:
     Analyzing bfId xxx
    <timestamp> [nn][bfdedup.c][1762][BfAnalyzeBitfile]:
     Bitfile xxx in pool Y was stored by a dedupable node(2)
    <timestamp> [nn][bfdedup.c][1823][BfAnalyzeBitfile]:
     Bitfile xxx is not an aggregate
    <timestamp> [nn][bfdedup.c][2410][BuildObjectListFromExisting]:
     Entering for super bitfile xxx
    <timestamp> [nn][bfdedup.c][2419][BuildObjectListFromExisting]:
     Error 1 from BfResolveSuperBitfile for bitfile xxx
    <timestamp> [nn][bfdedup.c][1853][BfAnalyzeBitfile]:
     Error 1 from BfGetObjectListForAggr for bitfile xxx
    <timestamp> [nn][bfdedup.c][2023][BfAnalyzeBitfile]:
     Exiting for bitfile xxx, rc: 1, numSkipped: 0
    <timestamp> [nn][bfdedup.c][6996][BfDedupVolumeThread]:
     BfAnalyzeBitfile returned rc 1, alreadyAnalyzed True, for
     bitfile xxx in pool POOLNAME.
    
    The loop is caused by the "Error 1 from BfResolveSuperBitfile"
    entry.
