ABSTRACT:
A plurality of heap dump requests associated with an operating virtual machine (VM) program is received from a VM profiler interface module at a heap dump request processing module. In response to receipt of each heap dump request at the heap dump request processing module, a dynamic modifiable library identified within a dynamic modifiable configuration file is loaded into a memory, where the dynamic modifiable library comprises instructions associated with processing a current heap dump request. The instructions associated with processing the current heap dump request are executed. The dynamic modifiable library is unloaded from the memory. A plurality of heap dump files and a plurality of object movement event files generated by execution of the instructions are analyzed. A memory leak associated with the operating VM program is automatically identified based upon the analyzed plurality of heap dump files and the plurality of object movement event files.
