[Zope] Data.fs Recovery

[Godwin Vaz]

Martin,

The file size is 2GB. Could that be the problem?

Yes I did stop and remove the index file and start again.

Workaround I followed:
Installed Zope 2.10.5 on my desktop (Win XP)
Dumped the Data.fs into the instance
Zope 2.10.5 happily ran through the Data.fs though with a few product 
missing errors
Copied the few missing products, the LDAPUserFolder is still a problem 
cannot import ldap module

Used the last Data.fs backup on the server and have manually started 
copying and pasting the source code for the missing pages.
