Workaround

JVM Heap Size Limitation

Although the JVM allows you to set heap size to values exceeding 2 GB, memory fragmentation and other Windows memory requirements typically limit the maximum contiguous address space available for Java applications to approximately 1.4 - 1.6 GB. For more information, see "Memory Support and Windows Operating Systems" at:

http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx

JVM configuration problem:

A problem occurs if version 1.3.1_06 or 1.3.1_08 of the Java 2 SDK is configured to run the Java HotSpot server VM (with the -server option).

Use the -hotspot option, which invokes the Java HotSpot client VM.

To invoke the HotSpot client to start your server, add the following line to your start script(s):

set JAVA_VM=-hotspot
