[Zope] can't pack large Data.fs (2.5GB)

Hi, can't pack a 2.5GB big Data.fs through the ZMI: ---------- Zope Error Zope has encountered an error while publishing this resource. Error Type: OverflowError Error Value: integer addition ---------- System: Debian woody with ext3 ---------- (Zope 2.6.2 (CVS 20030518 source release, python 2.1, linux2), python 2.1.3, linux2) Python Version 2.1.3 (#1, Sep 7 2002, 15:29:56) [GCC 2.95.4 20011002 (Debian prerelease)] System Platform ---------- If it was a LFS problem the zope wouldn't run. And I think the woody's python (Version: 2.1.3-3.2) is built with LFS support. Any ideas? Cheers, M.
