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.

Hi Nick,
Thanks for the suggestion.
We're already using a custom Engine class, so it shouldn't be too hard
to create a custom Pool.
Cheers,
Rudie.

Is there a way in Tapestry 3 to limit the maximum number of page
entries?
I don't think it's built in, no.
In Tapestry 4 there is the org.apache.tapestry.page-pool-max-active
setting, but it doesn't seem to be available for Tapestry 3.
Maybe any other suggestions on how to avoid this large number of
Bindings?
Not sure, but have a look in AbstractEngine:
* Returns an new instance of [EMAIL PROTECTED] Pool}, with the standard
* set of adaptors, plus [EMAIL PROTECTED] BSFManagerPoolableAdaptor} for
* [EMAIL PROTECTED] BSFManager}.
*
* <p>Subclasses may override this
* method to configure the Pool differently.
*
* @since 3.0
