Tapestry has been noted to be effectively free of memory leaks. What release of Tapestry are you using?
You seem to have a caching service here .. do you ever clear your cache? Could the contents of your cache account for the memory usage? Are you checking memory usage after running at least one full GC? If you aren't running out of memory, Java is happy to let it clutter up the place. You can use VisualVM to get an idea of what objects are in memory, that might help identify what, if anything, is leaking.
