Its quite well known issue that when you hot redeploy bigger webapp dozen of times you end up with out of memory exception. As far as I remember its related to garbage collection issues with Class class and its more related to Java than AS. Normaly - never use hot redeployment in production and increase heap size during development. Still I'm not saying there can't be any other bug causing memory leak.
