PyhtonAnywhere在Flask应用程序中超过了最大用户连接数

Question

I have a Python Flask web site running in PythonAnywhere. It runs fine for some time and then I start getting "User 'felipeavl' has exceeded the 'max_user_connections' resource (current value: 3) "

I am using SQLAlchemy and setting pool_recycle as advised in PythonAnywhere forums :

engine = create_engine(SQLALCHEMY_DATABASE_URI, pool_recycle=280)

I am also closing the session in all my flask methods, although SQlAlchemy was supposed to manage the connections, if I am not wrong:

def listarEmissores():
    session = DBSession()
    emissores = session.query(Emissor).all()
    session.close()
    return render_template('listar_emissores.html', emissores=emissores);

In my local MySql database everything runs fine. Am I missing any other configurations ?

You may have to email support at Pythonanywhere to get them to reset the connections on their end (as I had to). Otherwise, you will see I had the same issue (and my solution) at the bottom of the following page: How do I fix this Gets server error, which is causing display issues?
