Hi, I'm trying to use JPA persistence for a stateful session (version 5.1.1), the configuration is made using spring integration support. During the integration tests almost always I get an OutOfMemoryException. I chased the problem to the piece of code bellow (from org.drools.marshalling.impl.OutputMarshaller). The "for" statement marked "HERE" will cycle for ever (until no more memory is left). I also found the http://www.mail-archive.com/rules-users@lists.jboss.org/msg12427.html thread, I took out my split, but problem did not go away. Cheers, Dan case NodeTypeEnums.ForallNotNode : { if ( leftTuple.getBlocker() == null ) { // is not blocked so has children stream.writeShort( PersisterEnums.LEFT_TUPLE_NOT_BLOCKED ); ///////////// HERE for ( LeftTuple childLeftTuple = leftTuple.firstChild; childLeftTuple != null; childLeftTuple = (LeftTuple) leftTuple.getLeftParentNext() ) { stream.writeShort( PersisterEnums.LEFT_TUPLE ); stream.writeInt( childLeftTuple.getLeftTupleSink().getId() ); writeLeftTuple( childLeftTuple, context, recurse ); } stream.writeShort( PersisterEnums.END ); } else { stream.writeShort( PersisterEnums.LEFT_TUPLE_BLOCKED ); stream.writeInt( leftTuple.getBlocker().getFactHandle().getId() ); } break; } -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/OOME-on-JPA-persisten...
