Hello Aleksey,

I did some research and found that this problem might be connected with the
way SQLAlchemy works with it's connections, leaving some of them open which
causes this error. So, you can try explicit session closing
(session.close() or even session.remove()) at the end of each request (look
at load_db_driver() method). Updating SQLAlchemy and psycopg2 might work,
as well.
