 store.memory = 2000000

(2 Mb, add zero at the end)
I have an idea on what might causes the trouble, but I need more tests
to find out what the right solution would be... Try playing around with
heap-size and store.memory combinations and tell us what you get. 

the exception won't probably go away, but I'm interested in knowing how
many pages you were able to serve before this happens, depending on your
JVM memory + store.memory perameters.

No, it's not a memory leak. (pretty hard to do a memory leak in java)

It's a design flaw in the Java API that I had to program around in a
pretty nasty way... and sometimes it fails. Take a look at the store
classes if you care to know more about it.

Anyway, more tests will probably help us find out a better solutions
because i agree: what we have today does not scale as I would like to.

NOTE: cocoon2 will do much better being SAX based, but we still need a
better memory store model.
