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)

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:
quote

2007-05-04T16:20:36 (127.0.0.1:38127) received handshake 'Z303'
/quote
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
