Hi ! I get the error message again in Zope 2.7.1. Seems to be session error. Sessionmanager is say that "neworexisiting" key is not found, and make errors in transience module. The event.log is say that: 2004-07-20T16:32:35 ERROR(200) ZODB Couldn't load state for 0000000000000e80 Traceback (most recent call last): File "c:\zope\lib\python\ZODB\Connection.py", line 562, in setstate self._set_ghost_state(obj, p) File "c:\zope\lib\python\ZODB\Connection.py", line 607, in _set_ghost_state setstate(state) File "c:\zope\lib\python\Products\Transience\Transience.py", line 881, in __setstate__ new_slices = getTimeslices( AttributeError: _period ------ 2004-07-20T16:32:35 ERROR(200) ZODB Couldn't load state for 0000000000000e80 Traceback (most recent call last): File "c:\zope\lib\python\ZODB\Connection.py", line 562, in setstate self._set_ghost_state(obj, p) File "c:\zope\lib\python\ZODB\Connection.py", line 607, in _set_ghost_state setstate(state) File "c:\zope\lib\python\Products\Transience\Transience.py", line 881, in __setstate__ new_slices = getTimeslices( AttributeError: _period ------ 2004-07-20T16:32:35 ERROR(200) ZODB Couldn't load state for 0000000000000e44 Traceback (most recent call last): File "c:\zope\lib\python\ZODB\Connection.py", line 562, in setstate self._set_ghost_state(obj, p) File "c:\zope\lib\python\ZODB\Connection.py", line 607, in _set_ghost_state setstate(state) File "c:\zope\lib\python\Products\Transience\Transience.py", line 881, in __setstate__ new_slices = getTimeslices( AttributeError: _period When I try to change server to 2.7.3.b, it is drop another errors: 2004-10-01T17:30:30 ERROR(200) ZODB Couldn't load state for 0x0e44 Traceback (most recent call last): File "c:\zope\lib\python\ZODB\Connection.py", line 600, in setstate self._set_ghost_state(obj, p) File "c:\zope\lib\python\ZODB\Connection.py", line 645, in _set_ghost_state setstate(state) File "c:\zope\lib\python\Products\Transience\Transience.py", line 977, in __setstate__ oldlength = state['_length'] KeyError: '_length' ------ 2004-10-01T17:30:31 ERROR(200) ZODB Couldn't load state for 0x0e44 Traceback (most recent call last): File "c:\zope\lib\python\ZODB\Connection.py", line 600, in setstate self._set_ghost_state(obj, p) File "c:\zope\lib\python\ZODB\Connection.py", line 645, in _set_ghost_state setstate(state) File "c:\zope\lib\python\Products\Transience\Transience.py", line 977, in __setstate__ oldlength = state['_length'] KeyError: '_length' ------ 2004-10-01T17:30:31 ERROR(200) ZODB Couldn't load state for 0x0e44 Traceback (most recent call last): File "c:\zope\lib\python\ZODB\Connection.py", line 600, in setstate self._set_ghost_state(obj, p) File "c:\zope\lib\python\ZODB\Connection.py", line 645, in _set_ghost_state setstate(state) File "c:\zope\lib\python\Products\Transience\Transience.py", line 977, in __setstate__ oldlength = state['_length'] KeyError: '_length' ------ 2004-10-01T17:30:31 ERROR(200) SiteError http://kepes/manage_findResult Traceback (most recent call last): File "c:\zope\lib\python\ZPublisher\Publish.py", line 101, in publish request, bind=1) File "c:\zope\lib\python\ZPublisher\mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "c:\zope\lib\python\ZPublisher\Publish.py", line 39, in call_object result=apply(object,args) # Type s<cr> to step into published object.

But when I try to show anything to my boss with his IE, the Zope is "crashed". I say crashed, because I must restart it to work it again... (And the too many computer user use IE... :-( ) The 2.7.3b is buggy, so I don't have any chance, only downgrade. Please help me: Is the 2.6.4, or 2.6.3 is have this problem ? Is 2.6.4RC2 working good ? I must downgrade, but I don't know, what the version I choose to eliminate these session errors. Thanx for help: ft
