<br>
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. <br>
<br>
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'). <br>
At some point the Plone instance wasn't accessible anymore, neither the
left bar menu on the ZMI, raising some <b>KeyErrors</b> as follows
(instance.log): <br>
<br>

KeyError: 'twikidb'</i><br>
<br>
<br>
This is how the zope.conf look like:<br>
<br>
<br>
<i><zodb_db main><br>
# Main database<br>
cache-size 5000<br>
# FileStorage database<br>
<filestorage><br>
path <instance>/var/filestorage/Data.fs<br>
</filestorage><br>
mount-point /<br>
</zodb_db><br>
<br>
<zodb_db twikidb><br>
# Contains the Twiki DB<br>
cache-size 2000<br>
<filestorage><br>
path <instance>/var/filestorage/twikidb/Data.fs<br>
</filestorage><br>
mount-point /Plone/twiki<br>
</zodb_db><br>
<br>
<zodb_db temporary><br>
# Temporary storage database (for sessions)<br>
<temporarystorage><br>
name temporary storage for sessioning<br>
</temporarystorage><br>
mount-point /temp_folder<br>
container-class Products.TemporaryFolder.TemporaryContainer<br>
</zodb_db></i><br>
<br>
<br>
<br>
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. <br>
<br>
Thank you!<br>
