When using persistent connections with PostgreSQL if the DB fails or is restarted Django will return the following error: {{{ 2014-02-15 14:33:07 [24868] [ERROR] Error handling request Traceback (most recent call last): File "/srv/webapps/myapp/local/lib/python2.7/site- packages/gunicorn/workers/sync.py", line 131, in handle_request respiter = self.wsgi(environ, resp.start_response) File "/srv/webapps/myapp/local/lib/python2.7/site- packages/django/core/handlers/wsgi.py", line 194, in __call__ signals.request_started.send(sender=self.__class__) File "/srv/webapps/myapp/local/lib/python2.7/site- packages/django/dispatch/dispatcher.py", line 185, in send response = receiver(signal=self, sender=sender, **named) File "/srv/webapps/myapp/local/lib/python2.7/site- packages/django/db/__init__.py", line 94, in close_old_connections conn.close_if_unusable_or_obsolete() File "/srv/webapps/myapp/local/lib/python2.7/site- packages/django/db/backends/__init__.py", line 462, in close_if_unusable_or_obsolete if self.is_usable(): File "/srv/webapps/myapp/local/lib/python2.7/site- packages/django/db/backends/postgresql_psycopg2/base.py", line 192, in is_usable self.connection.cursor().execute("SELECT 1") InterfaceError: connection already closed }}} Not sure if this is Django related or psycopg2 related. Here are few details about my configuration: Django==1.6.2 gunicorn==18.0 psycopg2==2.5.2 CONN_MAX_AGE is set to 600 Is this a bug?
