The site apache was consuming a lot more memory than intended. The memory usage seemed to grow with every request to the apache 2.2 process. This was caused by a bad mod_wsgi configuration. This config made each apache process create multiple python interpreters within a single process, one for each GUI page (views.py, ...). Apache 2.4 based systems were not affected by this.
