If the back-end application takes too long to respond, Apache will time-out. I have seen this in my own Ruby on Rails web applications when something takes a while to process. So the Trac software is definitely the problem here. Either the server it is on is slow, or the database is slow, or some really inefficient code is taking a while to do something on each request.
