> There are stale locks that happened when a transaction failed due to a replication timeout to its peer node.  The transaction contained grouped keys that were submitted to the primary owner.  During execution of one such transaction, there was a state transfer, which changed ownership of these keys.  
> Here's an example flow:
> The task executed and started a transaction.  Since it was not the primary owner, it sent a LockControlCommand to the new owner.  This call timed out, and a rollback was issued.  The local transaction is completed, but subsequent attempts to lock this key fail.
