                    Infinispan uses a distributed lock to maintain a coherent transaction log during state transfer or rehashing, which means that only one cache can be doing state transfer or rehashing at the same time.
                    This constraint is in place because more than one cache could be involved in a transaction.
                    This timeout controls the time to wait to acquire acquire a lock on the distributed lock.
