Under program execution environment, a file size of a heap dump is reduced which is acquired so as to detect memory leaks, and so as to investigate occurrence causes of the memory leaks. In order to provide a memory leak investigating means which can be used even in a large-scaled system, the below-mentioned heap dump acquiring method is provided: When a heap dump is acquired, only such an object within objects stored in a heap memory is outputted which is adapted to the following conditions: That is, in a condition (1), an object exists among objects which are newly produced within a designated time period, and in another condition (2), an object is present on a reference path defined from a root set to the object which satisfies the above-explained condition (1).
