My setup is as follows:
OS - FreeBSD 4.7-RELEASE-p28 (Virtual Private Server setup)
Python - 2.3.4
Zope - 2.6.3

Do you really mean Zope 2.6.3?
This would be a bit old. Few of us could look at the code
mentioned in your traceback (as we have much newer versions).

On line 620 of your .../ZODB/FileStorage.py,
you perform an IO operation on a file which is closed.

Determine which file this is and where it gets closed.

[Zope] ValueError: I/O operation on closed file

[Brian Hickey]

Hi all,

Relative newbie to Zope, trying to install Plone on 
FreeBSD. Have run into the following problem:
- I have followed the instructions as per the guide 
at http://www.netvironments.org/laurazWiki/InstallingPlone
- After copying the directories into the 
lib/python/Products directory, I restart Zope, and it doesn't throw any 
errors. However, on visitingmy website installation (which had been 
working fine up to the file copy and subsequent restart), I get the 
message:

Sorry, a site error occurred.

Traceback (innermost last): 

Module ZPublisher.Publish, line 150, in 
publish_module Module ZPublisher.Publish, line 114, in publish Module 
Zope.App.startup, line 175, in zpublisher_exception_hook Module 
ZODB.ZApplication, line 61, in __bobo_traverse__ Module ZODB.Connection, 
line 532, in root Module ZODB.Connection, line 140, in 
__getitemtraceback_info__: Module ZODB.FileStorage, line 645, in 
load Module ZODB.FileStorage, line 620, in _load ValueError: I/O 
operation on closed file 

My setup is as follows:
OS - FreeBSD 4.7-RELEASE-p28 (Virtual Private 
Server setup)
Python - 2.3.4
Zope - 2.6.3

Any help would be greatly appreciated,
Brian
