Error description

  • When a parent transaction performs runstats, it acquires catalog
    cache X locks and holds them until the end of UOW. Within the
    same parent transaction, before runstats, an Anonymous Block is
    prepared and an i-coord is forked off to handle a separate
    transaction, but it waits for the catalog cache locks held by
    its parent transaction. This results in an Anonymous Block
    deadlock.
