* version: 1.3 => 1.6 Comment: I'm seeing this in a Django 1.6.8 project served via uWSGI 2.0.9. The exception is: {{{ Traceback (most recent call last): File "/srv/myproject/local/lib/python2.7/site- packages/django/core/handlers/wsgi.py", line 194, in __call__ signals.request_started.send(sender=self.__class__) File "/srv/myproject/local/lib/python2.7/site- packages/django/dispatch/dispatcher.py", line 185, in send response = receiver(signal=self, sender=sender, **named) File "/srv/myproject/local/lib/python2.7/site- packages/django/db/__init__.py", line 91, in close_old_connections conn.abort() File "/srv/myproject/local/lib/python2.7/site- packages/django/db/backends/__init__.py", line 381, in abort self.rollback() File "/srv/myproject/local/lib/python2.7/site- packages/django/db/backends/__init__.py", line 180, in rollback self._rollback() File "/srv/myproject/local/lib/python2.7/site- packages/django/db/backends/__init__.py", line 144, in _rollback return self.connection.rollback() File "/srv/myproject/local/lib/python2.7/site- packages/django/db/utils.py", line 99, in __exit__ six.reraise(dj_exc_type, dj_exc_value, traceback) File "/srv/myproject/local/lib/python2.7/site- packages/django/db/backends/__init__.py", line 144, in _rollback return self.connection.rollback() django.db.utils.InterfaceError: connection already closed }}} I can reliably replicate it by running `ab` against the app and doing a postgresql restart in the middle of it. All future requests fail until the uWSGI process is restarted. I tried changing the `lazy-apps` option in uWSGI, but the issue persists. -- Ticket URL: <https://code.djangoproject.com/ticket/15802#comment:36> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
