Abstract
A method, system and computer program product for performing recovery of a single-threaded queue are disclosed. The method includes scanning a set of elements of the single-threaded queue to detect a cycle containing a first element, and, in response to detecting the cycle, determining a size of the cycle in terms of a number of elements contained the cycle. A second element of the set of elements of the single-threaded queue is located, which second element is previous to the first element by a number of elements equivalent to the cycle. An element causing the cycle is located by performing a detailed element scan starting at the second element and the single-threaded queue is recovered by storing an end-of-queue value in a forward link of the element causing the cycle.
