[Zope] POSKeyError nightmare

[Kevin Carlson]

Hi all,

Rather large message with tracebacks and all -- any help is greatly 
appreciated...

I have tried to rid a large Zope DB of a POSKeyError to no avail.  I 
have tried the method that traverses the folder which contains the 
offending object using try/except to catch the POSKeyError, but even 
those continually throw the error.  Below is the traceback:

-------------
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "error_finder.py", line 6, in error_finder
    for id, next_item in folder.objectItems():
  File 
"/home/zope/instances/primary/Products/BTreeFolder2/BTreeFolder2.py", 
line 369, in objectItems
    self.objectIds(spec))
  File "/opt/Zope-2.7/lib/python/Products/ZCatalog/Lazy.py", line 138, 
in __init__
    else: self._len = len(seq)
  File "/opt/Zope-2.7/lib/python/ZODB/Connection.py", line 559, in setstate
    p, serial = self._storage.load(oid, self._version)
  File "/opt/Zope-2.7/lib/python/ZODB/FileStorage.py", line 689, in load
    return self._load(oid, version, self._index, self._file)
  File "/opt/Zope-2.7/lib/python/ZODB/FileStorage.py", line 657, in _load
    raise POSKeyError(oid)
ZODB.POSException.POSKeyError: 00000000000e5fec

I also ran fsrefs.py and the output is below:

All of the objects that are causing the POSKeyError I believe to be 
coming from a single instance of a very large BTreeFolder2 instance.  
Can anyone offer any remedy to remove or repair the offending objects?

Thanks,

Kevin
