Hudson build always end up in "java.lang.OutOfMemoryError: Java heap space" error

I'm having a problem with the Hudson build slave which has got Windows XP and 4 GB RAM and in the batch file to call the JNLP I have specify like the following:

javaws -J-Xms1280m -J-Xmx1024m http://hudson-master.domain.com:8080/computer/Exige/slave-agent.jnlp

Why can't I give it more than 1 GB ?

The system is out of resources.
Consult the following stack trace for details.

If you have Master Slave configuration, you should specify the memory settings in the Manage Hudson->Configure system->Global properties

The kind of Environment properties present on Master are used in Slave too.

Please note: On 32-bit Windows, a Java VM cannot allocate more than about 1 GB. Don't ask me why, but that's the case (at least it's the case for the Sun JVM). You need a 64 bit system if you need more memory for your JVM. And a 64-bit JVM, of course.

The Xms should generally be lower than the Xmx

Is the build executed directly by the JVM of the slave agent? If you run a Maven build (for example), the slave agent can launch an external Maven process (with default Java Xmx).

So you should specify the MAVEN_OPTS parameter to ensure that Maven builds are always executed with a customized Xmx value.
