Why is Django leaking memory?
-----------------------------
Django isn't known to leak memory. If you find your Django processes are
allocating more and more memory, with no sign of releasing it, check to make
sure your ``DEBUG`` setting is set to ``True``. If ``DEBUG`` is ``True``, then
Django saves a copy of every SQL statement it has executed.
(The queries are saved in ``django.db.connection.queries``. See
_`How can I see the raw SQL queries Django is running?`.)
To fix the problem, set ``DEBUG`` to ``False``.
If you need to clear the query list manually at any point in your functions,
just call ``reset_queries()``, like this::
from django import db
db.reset_queries()
The admin site
