We recently have had a problem that seems to indicate a small
hole in ZODB (3.4) transaction management.
Here is the sequence of events:
We have got a repeated "ConflictError", until ZPublisher gave up.
After this, the ZODB connection seems to be in a strange state:
We get continuous
ERROR ZODB.Connection Close callback failed for
<ZODB.Mount.MountedConnectionCloser instance at 0x9653a28c>
ConnectionStateError: Cannot close a connection joined to a transaction
A 'Shared.DC.ZRDB.TM.TM' instance no longer registers with
Zope's transaction system (almost surely, because it "_registered" flag
is still set).
The relational database "behind" this TM gets very unhappy
with its never ending transaction....
No other entries in the logfile that could help to understand what
