Sounds like a very fun project.

It sounds like the cache system is getting overwhelmed. Check /Cocoon.xml
(if you have that magic URL enabled) on the server and see if the cache
and/or memory store have lots of repeated URLs in them - I've had similar
troubles with one of my local cocoon-1.5 installations (not running out of
memory, but cocoon seemingly caching things more than once, or caching
one-time querystring-based URLs). I used to pester Stefano about the cache
system from time to time but haven't had the time lately. Sounds like a
good problem for y'all to commit some resources towards fixing ;).

Oh, and you don't mention which XML parser and XSLT processor you're
using. That may be relevant.
