Hello.
I am experiencing a problem with ZODB-3.6.0 / Python 2.5, under Linux.
Each time I initialize a database, i get a DisconnectedError exception
in the client, with the following traceback:
<quote>
File "/home/pferreir/workspace/indico/code/code/MaKaC/common/db.py",
line 50, in __init__
self._db=MaKaCDB(self._storage)

storage.load(z64,'')

return self.rpc.call("loadEx", oid, version)

File "/usr/local/lib/python2.5/site-packages/ZEO/zrpc/connection.py",
line 621, in wait
raise DisconnectedError()
DisconnectedError

In the server side, I get:

What confuses me is that I though that a root object for the database
would be created by the client, and a DisconnectedError is raised before
that happens. What can be happening?
Thanks in advance,
Pedro
