Hi. This looks like a bug in simple controller logic to me. Filed an
issue for this:
http://issues.carrot2.org/browse/CARROT-684For now, you can replace the controller to use the pooled one:
final Controller controller = ControllerFactory.createPooling();
Apologies for problems, we'll work on this.
