I recieve the following error very *occasionally* from a couple of
different django apps running against Postgres (some backtrace
included for context):
File "/opt/django/trunk/django/db/models/query.py", line 188, in
iterator
cursor = connection.cursor()
File "/opt/django/trunk/django/db/backends/__init__.py", line 33, in
cursor
cursor = self._cursor(settings)
File "/opt/django/trunk/django/db/backends/postgresql/base.py", line
98, in _cursor
self.connection = Database.connect(conn_string, **self.options)
OperationalError: could not connect to server: No such file or
directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.
5432"?
It's not consistent, and I have not been able to successfully
replicate it. It seems to happen when the sites are receiving
traffic. I know it's a Postgres error, but I thought since a lot of
Django users deploy against postgres someone might know something
about this. This latest error came from an app running psycopg
against 8.1.11. I'm 95% confident I've seen the same error on an app
running psycopg2 against 8.2.5.
Is it really just a matter of tweaking the postgresql.conf
(max_connections et al)?
Thanks!
doug.
