Weblogic 10.3 Heap Size (does not allow 3072mb)

Has anyone experienced a similar issue? In tuning Weblogic 10.3 R27.6.0-50 for Windows, we were trying various values for the heap size.

Startup jRockit options:

[sourcecode language=“jscript”] -Xms1024m -Xmx1024m [/sourcecode]

We were setting both values to the same.

1024m = worked 2048m = worked 3072m = did not work 4096m = worked

Did anyone experience a similar problem in allocating? Is there something special about 3072MB?

Update from Sept. 28th, 2010: When we tried this additional property in the start-up parameter the 3GB option works: -XxcompressedRefs=0

You can learn more about that parameter here .
