Memory problem with NWDS

Dear Colleagues,

I use NWDS 7.31 on Windows 7 64 Bit with SAP JVM 6 and get the following error while using the SAP memory analyzer tool

in NWDS to open a 3.7 GB heap dump:

I have 8GB RAM and it should be no problem to parse the heap dump. It seems I simply need to increase the heap space.
In the folder where the executable SapNetweaverDevloperStudio.exe resides, the SapNetweaverDeveloperSudio,.ni file is configured as


C:\Program Files (x86)\SAP\SAP JVM 6 (61_REL i486 opt)\bin













I increased -Xmx, but unfortunately, if -Xmx is set to 1024m or larger, NWDS does not start anymore.

What should I do? According to the error message I get, I should increase -Xmx to at least 1.7GB.

Ideally, I want to increase -Xmx as much possible in order to parse very large heap dumps.

Maybe I should first increase the allowed heap size on OS level and then edit again the *.ini file?

Thank you and kind Regards
