ABSTRACT:
The present invention provides a method, system, and computer program product for light weight memory leak detection. A method in accordance with an embodiment of the present invention comprises: obtaining raw free memory statistics; approximating free memory after garbage collection from the raw free memory statistics; and analyzing the approximated free memory after garbage collection to identify a potential memory leak. A method in accordance with another embodiment of the present invention comprises the steps of: obtaining raw free memory statistics; generating a vector of memory leak indicators from the raw free memory statistics; comparing the vector of memory leak indicators against a plurality of vectors of the same memory leak indicators for known memory leak scenarios; and identifying a potential memory leak based on the comparison.
