  • Patent number: 8793289
    Abstract: A system and method are provided to inspect memory leaks and copy garbage collection files. In one embodiment, an original garbage collection file is selected from a plurality of garbage collection files at a file system. The original garbage collection file is periodically copied into a duplicate garbage collection file. The duplicate garbage collection file serves as a backup file to the original garbage collection file.

  • Patent number: 8229979
    Abstract: A system and method are provided to inspect memory leaks. In one embodiment, a method of inspecting memory leaks is disclosed. The method includes garbage collecting at a virtual machine to generate a garbage collection file having memory leak information identifying dirty objects of an application causing first memory leaks and providing a state of the dirty objects as they existed prior to causing the first memory leaks. The garbage collection file is periodically duplicated into a backup file to the garbage collection file, and, during runtime, the backup file having the memory leak information is analyzed including reviewing the state of the dirty objects as they existed prior to causing the first memory leaks to identify clean objects capable of turning dirty and causing second memory leaks.

  • Patent number: 7953772
    Abstract: A system method is provided to inspect memory leaks and analyze contents of garbage collection files. In one embodiment, a garbage collection file is selected from a plurality of garbage collection files at a file system. The garbage collection file includes histograms. Each histogram is compared with other histograms in the garbage collection file to identify objects associated with memory leaks The results of such comparison are provided.
