Hi All,
We have been facing the problem of heap dumps getting generated in our QA Env, the size of the dumps is over 1 GB and the format is .phd
We have tried various tools to analyze it including ones that are mentioned on IBM Website but get the following error
Opening '' as a 'Portable Heap Dump file' ...
Fatal exception : java.lang.Error: Unexpected error:
at HR.input.NPHDParserImpl.(
at HR.main.Launcher.openFile(
at HR.main.Launcher.main(

The other methods of using Memory Analyzer have also not yielded any success. In one of the tutorials, it was mentioned to write a class which would eventually leak memory and then run it using -XX:+HeapDumpOnOutOfMemoryError. I have the following Questions
1) Has anyone done an analysis of .phd formats over 1.5 GB, if yes - How
2) I have the entire source code from my project and write a class in it which leaks memory, the Memory Analyzer Report which I get does not show anything about the other classes that I have, What am I not doing correctly here
Please let me know

Another option that we are tying is to generate heap dumps in .txt format.

Hi Amit,
Even I am facing the same issue. Getting the same exception. If you were you able to resolve it, please let me know.
