Error when trying to analyze large heapdump

[Former Member]

Hi,

Tried both the standalone Eclipse Memory Analyzer and also the batch file. The heapdump file is 4GB. From the batch file I get this

Thx.

Hi,

please rename the file to something like heapdump.hprof. Then it should work.

The problem: it looks like we do not expect the heap dump to have no extension. I have opened an Bugzilla Bug. If you want to track progress, feel free to add yourself to the CC list: https://bugs.eclipse.org/bugs/show_bug.cgi?id=246853
