For some reason the object that was damage was inside a ZCatalog. Darned if I 
know why that key would refer to something in a ZCatalog. 

How I found it was I just tried to export one folder after another and worked 
my way down until I found that object as the one that would not export. Once 
I had it found I deleted it and just created another one and it works now.

So if anyone else runs into this problem and can't find the object if you do 
an export it will throw an error if it has the bad object in it so you can 
just export containing folders until you get the problem and then go down 
until you find the appropriate object.

[Zope] invalid load key

[William Heymann]

This is the traceback I am getting when I try to pack the db



Traceback (innermost last):
  Module ZPublisher.Publish, line 115, in publish
  Module ZPublisher.mapply, line 88, in mapply

How can I find out what object is damaged so I can fix it/remove it?

My best guess on what caused the problem was undoing a large set of deletes 
because someone deleted something they should not have and then deleting 
those objects again. I tried to run fsrecover.py on the db and it seems to 
just spin at around 99%. I will run it again and just leave it running and 
see if it ever finishes but I let it run for a pretty long time already.

Also any idea on what could have really caused the problem? memtest did not 
report any errors when I last ran it and the hard drive diagnostics don't 
report any issues either.

The Zope version is 2.9.5 and the db is about 2GB in size and the point at 
which fsrecover.py stalls is about the last 4 megs.

Thanks
