Hello everyone, *From time to time* I get the following exception in my web app deployed using mod_python:
ArgumentError: Class '<class '_mp_275338c85bf6e509c22a44d1e08ba3fd.Architecture'>' already has a primary mapper defined. Use non_primary=True to create a non primary Mapper. clear_mappers() will remove *all* current mappers from all classes. If I use sqlalchemy.orm.clear_mappers(), the problem goes away - however, it bugs me to see some evidence that mappers and possibly some other state is retained between http requests in mod_python. Does anybody know why / can it be harmful in some other way?
