4.1.2 has a robust page pool "built in" that expires pages automatically.

Hi Rudie. A few extra notes ... One problem was permgen being filled by Tapestry's class creation/instrumentation, and the other is that the default Pool only adds pages - it never removes or limits them. If you check old Tapestry 3 era posts about "out of memory" you'll also see some recommendations for JVM settings: -XX:MaxNewSize=300m -XX:MaxPermSize=300m Also for Tapestry 4(.0?) Henri Dupre created a "SoftPool" that used SoftReferences which solved his memory problems. You could also enable the cache/pool reset service. HTH. Cheers, Nick.
