There are several hints about a memory leak in Ant related to not cleaning up classloaders used for loading typedefs/taskdefs in subbuilds. So far we haven't pinned down the problem. Are you defining the dbunit tasks inside the <for> or are you spawning new <ant> or <subant> ot <antcall> tasks inside <for> that would do so? If so you may be able to work around the problem by defining the tasks inside the main build before the for loop. The other things you may be leaking are JDBC drivers. You could try to load the driver inside the main build explicitly so it never ends up on any other classloader (<available> should help).
