Memory leak diagnosis

A method for diagnosing a memory leak, the method comprising:

• tracing allocation of at least one object performed at runtime on a virtual machine, the object being created by an application program wherein the tracing including:
• acquiring corresponding allocation paths and corresponding allocation times of the objects;
• and recording the corresponding allocation paths and the corresponding allocation times of the objects, with the recording comprising assigning a unique identifier (ID) to each of the objects corresponding to the allocation path;
• counting age generations of the objects of a similar type based on the corresponding allocation paths at a preset time interval;
• identifying a suspicious allocation path having the objects with high age generations;
• and
• reporting the suspicious allocation path to a user, wherein the user analyzes the objects with suspicious allocation paths to be a cause for the memory leak;
• wherein the assigning further comprises aggregating a band ID and a group ID of each of the objects, wherein the band ID and the group ID are related to the allocation path into a tag, and binding the tag with the corresponding object, wherein the tag further includes information about a type of the corresponding object, the allocation path, an address pointing to a storage of a method signature and a callee.
