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:

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.loadEx(oid, version)[:2]

File "/usr/local/lib/python2.5/site-packages/ZEO/ClientStorage.py", line 769, in loadEx
   data, tid, ver = self._server.loadEx(oid, version)

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

File "/usr/local/lib/python2.5/site-packages/ZEO/zrpc/connection.py", line 531, in call
   r_flags, r_args = self.wait(msgid)

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
