A 404 means that the script in the webpage is calling for a resource that doesn't exist (or could have been moved and the link has not been updated)
Given that the site has been down for maintenance several weekends in a row now, it looks like a developer has 'broken' a link somewhere, though why it would take months to fix is beyond me.

(Apache) Tomcat have now moved to version 7, the version in use by that mail server is extremely dated in some respects (at least 3 years old), so it could be a lack of resources causing a failed return, 'server overload' if you like.
Being intermittent this would seem most likely, though is perhaps the hardest to pin down.
