Abstract

Techniques for tracking memory usages of a data processing system are described herein. According to one embodiment, a memory manager is to perform a first lookup operation in a memory allocation table to identify an allocation entry based on a handle representing a memory address of a memory block allocated to a client and to retrieve a trace entry pointer from the allocation entry. The memory manager is then to perform a second lookup operation in a memory trace table to identify a trace entry based on the trace entry pointer and to increment a memory allocation count of the trace entry. The memory allocation count is utilized to indicate a likelihood of the client causing a memory leak.
