Abstract:
Embodiments of the invention provide systems and methods for analyzing memory heap information for investigation into a memory leak caused by an application. According to one embodiment, a method of analyzing heap data can comprise obtaining the heap data from a memory. The heap data can represent a plurality of objects of one or more classes, each object identifying a referrer instance, a field in the referrer, and a referent instance. A statistical analysis can be performed on the heap data to identify objects within the heap that are contributing to a growth of the heap. The heap can be traversed based on the referrer instance of one or more objects identified as contributing to the growth of the heap to a root object identified as not contributing to the growth of the heap.
