A lock manager running on a machine may write a first entry for a first process to a queue associated with a resource. If the first entry is not at a front of the queue, the lock manager identifies a second entry that is at the front of the queue, and determines whether a second process associated with the second entry is operational. If the second process is not operational, the lock manager removes the second entry from the queue. Additionally, if the queue becomes unavailable, the lock manager may initiate failover to a backup copy of the queue. |
