Use ZooKeeper to maintain the population of Transaction IDs. ZooKeeper's ephemeral nodes are ideal for lock management. and TXID is a node. It is locked if it has a child ephemeral node called 'lock'. If the client dies, the node is deleted, releasing the Transaction ID. The protocol that guarantees one client locks a TX node follows the recipe for locking, where the ephemeral node with the smallest sequence number wins.
