[Zope3-Users] zodb is growing every login/logout

[Jens]

@Paul: yes, ZODB just grow after login and logout.

@Nikolay: Yes, I'm using the default persistent zope3 session. This was
also my first idea, and I switched to a RAM Session, but it had no effects.

I tested the RAM Session by restart zope, and I where logged out after
restart (so I think the RAM session is working by losing the
login-data). But the ZODB was growing again.

Here is my code to switch the session and my session class:

-------------------------------------------------------------
#from zope.session.session import RAMSessionDataContainer
from zope.session.session import PersistentSessionDataContainer

class MySession(PersistentSessionDataContainer):
  timeout=5*60*6
  def __init__(self):
    super(MySession,self).__init__()
    # timeout session 5 minuten:
    self.timeout=MySession.timeout
    self.resolution=1*60
---------------------------------------------------

But i switched just in the app, maybe I have to change the global
session in zope?

Thanks for your help
Jens
