    From the callstack, the backup session created the bitfile and
    attempted to deallocate the memory segment. During the
    deallocation of memory segment it found an overflow condition
    and then it attempted to check the super node participation
    using BvCheckSNodeParticipation function which failed and
    reported below message with RC 257.
