If you add "Output:Diagnostics,DisplayExtrawarnings" to your input file you can usually get enough information to diagnose the problem. Often the problem is just edges of surfaces that are not lined up. Generally, you should confirm if the zone volume being used in the simulation is what you expect. If it is then it is not a problem. The zone volume is only used in a few places related to airflow. Also note, the algorithm that determines if the volume is not enclosed is not full proof and sometimes shows something is wrong when it is not.
