[Ape] APE issue

I've been trying to migrate a 5GB ZODB onto APE/filesystem. It's worked
fine on the whole but I've had a few issues:
First, a dozen or so of files in the ZODB are quite large, 100MB-200MB. I
know that neither ZODB nor APE are really designed for files of this size
but it works fine under ZODB although it is a little slow sometimes.
However under APE we frequently get 'out of memory' errors - both when
creating and viewing the files. The server has 4GB of RAM plus swap space
and I was the only user at the time so I am surprised that a 100MB file
causes this error. Unfortunately there is no traceback in the log - I
guess that running out of memory stops the logging.
Secondly, I've occasionally had 'maximum recursion depth exceeded'
messages when pasting content. This is when pasting 4 or 5 files.
Traceback appended. This looks to me like a problem with Archetypes and
the Pickler rather than APE per se. But again, it has never happened with
the ZODB. Increasing Python's maximum recursion did resolve the issue.
I'd be grateful for any ideas on either of these issues.
