Errors while trying to rename or delete unused tags

edit

Hi,

As listed here: http://askbot.org/en/question/2673/is-there-a-way-to-purge-unused-tags-from-the-db/ , I tried to run the tag commands. I'm not sure if it works. It seems to error out:

[root@ask01.stg config]# python manage.py delete_unused_tags
/usr/lib/python2.6/site-packages/django/db/__init__.py:19: DeprecationWarning: settings.DATABASE_* is deprecated; use settings.DATABASES instead.
  DeprecationWarning
/usr/lib/python2.6/site-packages/django/db/__init__.py:60: DeprecationWarning: Short names for ENGINE in database configurations are deprecated. Prepend default.ENGINE with 'django.db.backends.'
  DeprecationWarning
WARNING!!! You are using a 'locmem' (local memory) caching backend,
which is OK for a low volume site running on a single-process server.
For a multi-process configuration it is neccessary to have a production
cache system, such as redis or memcached.

With local memory caching and multi-process setup you might intermittently
see outdated content on your site.

Searching for unused tags:

django.db.transaction.TransactionManagementError: Transaction managed block ended with pending COMMIT/ROLLBACK

Is this working? It said it didn't find any unused tags but still spews the trace back. A similar error is spewed while using the other tag commands too.

Update:

I've googled and the error seems to be quite common:

Does this happen on askbot.org? I'm running this without switching off the website.
