thanks thomas.

the ``<gen>`` option is set::

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>gwt-maven-plugin</artifactId>
            <version>${org.codehaus.mojo.gwt-maven-plugin.version}</
version>
            <!-- at this point there are no modules to configure. all
real modules
                 are configured in subprojects. -->

            <configuration>
                <!--

                <extraJvmArgs>-Xmx2048m -XX:MaxPermSize=1024m -

                <strict>true</strict>
                <logLevel>${com.google.gwt.logLevel}</logLevel>
                <style>OBF</style>
                <mode>htmlunit</mode>
                <testFailureIgnore>false</testFailureIgnore>
                <testTimeOut>120</testTimeOut>
                <generateDirectory>${root.basedir}/vz-gwt-main/target/
generated-sources/gwt</generateDirectory>
                <gen>${root.basedir}/vz-gwt-main/target/.generated</
gen>

i will try ``<timeout>`` but i'm pretty sure there will be no
success.

the point is: on a 4-core buildbot with identical os installed and
identical build settings, the same project succeeds building. its
always during the permutations where a 16-core machine fails.

we tried this with a virtualized centos a few weeks ago, now we just
tried a real production hp g6 machine with rhel 6.1 installed. the
environment was deployed via jenkins.
