ConflictError: database conflict error (oid 0x0b01, class Products.zms.zmstrashc

Hi,

my Zope slows down it's performance immediately after startup. After a
few clicks it's not responding anymore. I switched to debug mode and
found the following errror message in the event.log file:
-------
2007-10-25T11:59:07 BLATHER Conflict traceback

What can I do?

Cheers
