heap space problem with surefire unit tests

HI,
I'd really appreciate any help with the following.
I run a single unit test in Eclipse without any problems. 
Running the same unit test through Maven, without eclipse running, fails
with the following message:
ERROR!
java.lang.OutOfMemoryError: Java heap space
java.lang.OutOfMemoryError: Java heap space

I've tried the following surefire configuration based on similar message in
this forum:

<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-plugin</artifactId>
				<version>2.3</version>
				<configuration>
					<forkMode>none</forkMode>
					<argLine>-Xms256m -Xmx512m -XX:PermSize=512m
-XX:MaxPermSize=512m</argLine>
					<disableXmlReport>true</disableXmlReport>
				</configuration>
			</plugin>


Thanks in advance.

OK. The problem was the fork command. Remove the fork and the heap space
problem no longer occurs.
