A method and apparatus of partitioned memory dump in a software system is provided, the apparatus comprising: a monitor for, during the execution of the software system, monitoring the memory allocations and deallocations of objects in the software system and according to the results of the monitoring, assigning the allocated objects in the software system into corresponding memory partitions, wherein the memory space of the software system is partitioned according to a given partitioning scheme; an event detector for detecting a triggering event of memory dump; and a dumper for dumping related memory partitions according to the detected triggering event of memory dump. Preferably, the apparatus further comprises an analyzer for analyzing the dumped information, and generating a new dump triggering event or a new partitioning scheme based on the analysis results.
