Error description

  • It is possible that the subtransaction works on a tablespace
    with ID > 4096 and in that case the subtransaction will allocate
    a second dirty pool bitmaps, but the main transaction does not,
    that is, the main transaction has NULL pointer for this dirty
    pool bitmaps. When we merge dirty pool bitmaps of
    subtransactions into the main transaction, this will cause a
    trap.
