I have set up our Zope at https://register.funcom.com to email me whenever errors occur, and during the christmas holidays we got the following strange reports : The billing Zope at register.funcom.com reports an error The error is: KeyError : 1040726440 TRACEBACK: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PythonScripts.PythonScript, line 315, in _exec Module Script (Python), line 4, in index_html <PythonScript at /newuser/index_html> Line 4 Module ZPublisher.HTTPRequest, line 1189, in __getattr__ Module ZPublisher.HTTPRequest, line 1149, in get Module Products.Sessions.SessionDataManager, line 93, in getSessionData Module Products.Sessions.SessionDataManager, line 180, in _getSessionDataObject Module Products.Transience.Transience, line 175, in new_or_existing Module Products.Transience.Transience, line 786, in get Module Products.Transience.Transience, line 599, in _getCurrentBucket Module Products.Transience.Transience, line 688, in _housekeep KeyError: 1040726440 i got a lot of these reports successively , all with the same key-error, until i restarted the server. It seems to have happened to a series of different users (different IPs , browsers, etc in the REQUESTS) The problem has not reappeared since the 24th of December, but i would really like to figure out what caused it.. Has anyone experienced anything like this?
