Info Messages Off

RooFit has an annoying habit of giving far more information than is actually useful, which actually makes it difficult to find the important error messages. The best approach is just to turn off the unimportant error messages with this command:

RooMsgService::instance().setGlobalKillBelow(RooFit::WARNING);

This shuts off all error messages with significance less than WARNING. See the root forum below:
