I submitted a ticket at webfaction, this is their reply: "That is correct, this does not completely prevent the problem from recurring. Using a static-only symlink app is just a step in helping with the memory usage. In order to solve the memory issue, you would need to find the root cause of the memory usage. You can do this by following the steps outlined here: http://docs.webfaction.com/software/general.html?highlight=memory %20usage#reducing-memory-usage
Using Nginx+uwsgi may reduce your memory usage, but it will involve some experimentation with your application. If you want to try installing Nginx+uwsgi, I would create a new application and try the installation following the steps outlined in that community post. This way you can still have your existing site online while you are install the new uwsgi application. The technologies are similar, but uwsgi is newer and has been known to use less memory." Annet.
