I have used both Tapestry and HiveMind under high production loads and have never found any memory leaks in the frameworks themselves. This includes memory intensive, high volume workflow and image processing applications for large financial institutions.
However, nearly every application I have worked on has experienced memory leaks at times, often times severe. Sometimes it was my own code. Often it was 3rd party libraries like caching frameworks (ehcache constructs had a badly leaking MutexCache implementation - fixed last year), dao frameworks (iBatis had an LRU cache which did not properly invalidate every other expired entry - also fixed), JDBC drivers (just worked with a version of an AS/400 driver which leaked live a sieve - recently fixed), and the JDK (StringBuffer in 1.4 anyone? - how about using Java 2D?). My experience tells me that if you haven't run your application through JProfiler and looked for leaks, there is a *very* good chance your app is leaking memory, often times in unexpected places. Just because your application is a Tapestry application does not mean the leak is caused by Tapestry - odds are against you on that. My suggestion would be to run your application under JProfiler and put some load on it. It is very simple to do. Watch the heap telemetry and see if it grows monotonically. Watch the object allocations and sizes for the same. If you have some empirical evidence to support a suspected leak in Tapestry, then present it here. I assure you Jesse and the other developers would be eager to fix them.
