Comment 13 Roy Reznik 2016-09-14 07:38:32 EDT Hi, As a workaround, I used https://github.com/geoff-addepar/heap-dump to parse the core dump and found it to be working well. Source

I just checked the scripts, but I couldn't find any -Xmx parameter. From my experience you can get for -Xmx at maximum between 1200M and 1500M.

How can I get a heap dump? Debugger attached successfully. Thanks, M. The number differs from machine to machine, as it also depends on the fragmentation of the 2G by the different loaded dlls.

Give it some more memory" –wojand Mar 26 '12 at 7:22 add a comment| up vote -1 down vote An internal error has occurred. Until now, I didn't check for this unexpected value that's why the Analyzer threw the NPE later on. The second patch tries to use the same approach that is used by e.g. I've hit the "Computing retained sizes" hang issue in jvisualvm a few times now.

The tools needs (a) a 5.0 JRE and (b) SWT platform binaries. http://dukesoftwaresolutions.com/an-internal/an-internal-application-error-occurred-java-lang-nullpointerexception.html SAP Notes for the different IBM platfomrs are available on the "How can I get a heap dump" page. Check out our blog, the WIKI and the forum. Anyway, I'll have to figure out if we ignore the error or improve error reporting and bring a clear message instead of NPE.

There are some inconsistencies inside - so far I have one object record, which contains a classId not included in the dump. Read what our users have to say!

Also, we now have a forum which can be used for questions and answers.

That's what i meant. I have implemented some changes, so that our future versions are able to work with jmap-produced dumps despite of the mentioned differences. Once the heap dump is parsed, you can re-open it instantly, immediately get the retained size of single objects and quickly approximate the retained size of a set of objects. We will see what we can do for you.

Good luck, Roy.
