[ZODB-Dev] Invalid object references on brand new Data.fs using fsrefs.py

[Ross, Troy D]

Hello,
  I just created a brand new instance of a Zope 2.9.3, started the
instance once so that it creates a Data.fs file and then gracefully shut
down the zope server.  I then ran fsrefs.py on Data.fs and I was given
the following results:

oid 0x0L persistent.mapping.PersistentMapping
last updated: 2006-07-26 21:48:47.904932, tid=0x36714FCCC64F5DDL
refers to invalid objects:
        oid ('\x00\x00\x00\x00\x00\x00\x00\x01', None) missing:
'<unknown>'
        oid ('\x00\x00\x00\x00\x00\x00\x00\n', None) missing:
'<unknown>'
...

oid 0xA79L BTrees._IOBTree.IOBTree
last updated: 2006-07-26 21:48:54.163685, tid=0x36714FCE7193011L
refers to invalid objects:
        oid ('\x00\x00\x00\x00\x00\x00\nz', None) missing: '<unknown>'
        oid ('\x00\x00\x00\x00\x00\x00\n{', None) missing: '<unknown>'
        oid ('\x00\x00\x00\x00\x00\x00\n|', None) missing: '<unknown>'

Similar load errors were repeated for a total output of 6713 lines.
 
Are these references that don't refer to pickled objects supposed to be
in the Data.fs file? I've run earlier version of zope and I never saw
such load errors. The system is running FreeBSD 6.1 with python 2.4.3.
I tested a similar setup on a Windows XP machine with similar results.

Thank you,
