Hi Dieter,
thanks for this hint.

In our private Zope version, I have still a note like this:
# DM 2005-08-22: always call '_flush_invalidations' as it does
# more than cache handling only
self._flush_invalidations()
if self._reset_counter != global_reset_counter:
# New code is in place. Start a new cache.
self._resetCache()
# DM 2005-08-22: always call '_flush_invalidations'
## else:
## self._flush_invalidations()
The note indicates that the bug was fixed at least at 2005-08-22
(though the handling was not completely right in case the cache
was reset).
In ZODB.Connection.Connection.open I see:
if self._reset_counter != global_reset_counter:
# New code is in place. Start a new cache.
self._resetCache()
else:
self._flush_invalidations()
So self._flush_invalidations() is only called in the else-condition.
In your patch it is always called. I try your version and report back.
