Hello,
This is the first time I write in this list, looking for some advice to
solve the problems we have encountered in our Zope enviroment.
We are running a non-zeo Zope 2.9.8 with 2 databases (the main ZODB and
a mounted database, called 'twikidb', via ZODB Mounted point, within a
Plone instance on an object called 'twiki_import').
At some point the Plone instance wasn't accessible anymore, neither the
left bar menu on the ZMI, raising some *KeyErrors* as follows
(instance.log):
/2008-07-08T14:12:30 ERROR ZODB.Connection Couldn't load state for 0x2762

KeyError: 'twikidb'/
This is how the zope.conf look like:
/<zodb_db main>
# Main database
cache-size 5000
# FileStorage database
<filestorage>
path <instance>/var/filestorage/Data.fs
</filestorage>
mount-point /
</zodb_db>
<zodb_db twikidb>
# Contains the Twiki DB
cache-size 2000
<filestorage>
path <instance>/var/filestorage/twikidb/Data.fs
</filestorage>
mount-point /Plone/twiki
</zodb_db>
<zodb_db temporary>
# Temporary storage database (for sessions)
<temporarystorage>
name temporary storage for sessioning
</temporarystorage>
mount-point /temp_folder
container-class Products.TemporaryFolder.TemporaryContainer
</zodb_db>/
Any idea on how to fix this? I would unmount the database 'twikidb' if
needed, even delete the object related. The most important thing is
getting back the Plone instance and the ZMI.
Thank you!
