See full text

A computer-implemented method includes performing, by each of a plurality of crawlers, a random walk of a plurality of objects in a heap, where the plurality of objects are memory objects allocated for execution of an application. A timestamp of each object of the plurality of objects is updated, when the object is visited by a crawler of the plurality of crawlers. Garbage is identified, by a computer processor, based at least in part on the timestamp of each object of the plurality of objects. The garbage is reclaimed.
