> ProtobufLengthDecoder.decode() does call OutOfMemoryHandler.handle() which
> calls DataResponseHandlerImpl.informOutOfMemory() which just logs the error
> in the logs.
> If we have fragments waiting for data they will be stuck waiting forever, and
> the query will hang (behavior observed in DRILL-3241
