[Zope] Zope fails on large task?

[Peter Bengtsson]

Can you check your memory consumption on the server? It could be that
your application eats up so much memory that your zope can't handle it
and thus times out.
If this is the case you'll need to rewrite your app to NOT create a
too big data structure of dictionaries.
