We're running Zope 2.6.1, has the issue gone away on Zope 2.6.2? I just checked in a change that disables the low conflict connection feature of temporary storage. This fixes the KeyError issue out of 'get', but others have reported a problem for which the symptom is a a KeyError out of the storage's 'load' method. I have not been able to reproduce this problem. In that thread a patch to TemporaryFolder.py was suggested to deal with ReadConflictErrors, but we don't get those. The suggestions regarding the KeyErrors was: 1) to move to a different storage, such as BerkeleyStorage or DirectoryStorage, for the session data, or 2) to touch the objects that are likely to change early in the transaction. (Toby Dickenson). Our errors are triggered in the bowels of XMLWidgets, so I don't think 1) is a simple solution, and we don't want to do 2) if we can avoid it. Have specific alternative session storages been found to be free of this issue? You can give it a shot. The problem definitely seems to be related to the TemporaryStorage class, which won't be used if you use a different storage. The initial report has been logged as a 'critical' error as http://collector.zope.org/Zope/848 but it's still Pending. I have commented on the issue.

Re: [Zope-dev] The Return of the Son of Session Errors, redux
Hi Chris I just checked in a change that disables the low conflict connection feature of temporary storage. We've patched, and so far it looks good. We've seen one KeyError, but that was after leaving the session to expire. Will 2.6.2 get the patch?
