Just out of curiosity...do you know how many xml files there are? Is it possible there are a ton?

Hi,

i'm getting OutOfMemory-Errors while executing a fileset-task.
My Buildfile looks like this:

<project name="foo" default="bar">
    <target name="bar">
        <mkdir dir="${basedir}/logs/temp"/>
<move failonerror="false" flatten="true" todir="${basedir}/logs/temp"> 
            <fileset dir="${basedir}/myDir">
                <include name="**/*.xml"/>
            </fileset>
        </move>
        <xslt basedir="${basedir}/logs/temp" destdir="${basedir}/logs"
extension=".xml" includes="*testresult*"
style="/build/configs/cppunittransform.xsl"/>
    </target>
</project>


This is what ant generates when i'm running the buildfile:

There are some folders under "${basedir}/myDir". But the strange thing is, if I 
set it to a directory with no subfolders, the thask performs very well.
I've already set the maximum heap-space to 500m, but that doesn't helps. 
I changed my jvm to 1.4 with the same result.
Has anybody an idea how to fix that?

I am not quite sure if this will help but once I read about such a
problem(although it was in Ant 1.6.4.) and solution was to set the
"ANT_OPTS" environment  variable to "-Xmx256m".

I have already set the maximum available memory to 256m and 512m. The only difference is the time it takes to fail with the OutOfMemoryError. Because of 
that it looks like a memory-leak.
