Hmmm, can you try disabling the cache and report back?

Need OS, JVM and servlet engine to tell you something. Cocoon can hardly
be the source of any instability, unless you run out of memory.

In Cocoon1, this happened for OutOfMemory exceptions what went lost.
Cocoon1 is a slow beast but a very polished one.
Cocoon2 is going to be lightyears ahead on most things, but it's not
that polished on its internals. This doesn't mean it's not ready for
production, but you can't match the 1.8.2 release in terms of
polish-ness.
At the same time, I don't expect Cocoon 2.8.2 to be as polished as the
old one, I expect Cocoon 2.1 to be, but we have to release to have more
feedback from production sites because it's a catch22 problem: without a
final release, few people use it for production thus give not much
feedback on us on how to make it fast and scalable.
