Title: Apparatus, system, and method to prevent queue stalling

Abstract: An apparatus, system, and method are disclosed to prevent queue stalling. The apparatus to prevent queue stalling is provided with a plurality of modules configured to functionally execute the necessary steps of detecting a connection failure on a first logical path, wherein the first logical path is associated with a first entry in a queue, and wherein the first logical path is configured to define a communication path between an entity associated with a first entry in the queue and a queue manager, scanning the queue to identify a second entry associated with a second logical path in response to the connection failure, and advancing the second entry to a position within the queue that is ahead of the first entry. These modules in the described embodiments include a detection module, a scanning module, and an advancing module.
