java.lang.OutOfMemoryError on Vista

[Former Member]

Hi,

I have a very memory-hungry standalone Java application. At the moment, I cannot re-design it. Thus, it still has to run a little while.

Problem: when I start it with -Xms512m or -Xmx1536m it runs into a java.lang.OutOfMemoryError !

I suspect that the OS cannot allocate enough memory - what is strange:

Vista-32bit, 10 GB pagefile, 3.5 GB RAM, JRE 1.6.0_11

Any comments appreciated - thanks !

Bernie
