So, after I did some restructuring (we throw out some depend-attributes on targets that get called via antcall) and after the recompilation of ANT the build runs fine, even with CruiseControl. The build was running, after the restructre, smoothly, but when we run the build via CC we still got memory errors. After the recompilation of ANT now everything is fine.
Thanks to all :-)

R,

Markus
