It is because you are using a very old version of mod_wsgi. The problem started when they made a change in how Python does cleanup on shutdown.
If you cannot upgrade to a newer mod_wsgi version (latest is 3.4), then at least add the following directive to Apache: WSGIRestrictedEmbedded On This will stop Python being initialised in the main Apache worker processes, which is where the message is likely coming from because of process churn with your Apache configuration and MPM choice. If that causes stuff to fail in other ways, then likely you aren't actually delegating applications to the daemon process properly. In that case make sure you always have WSGIProcessGroup set appropriately.
