Turned out to be problem with the application. Somehow (I do not know yet know how or when) an object derived from OOBTree got corrupt. Corrupt in the sense that although looking up individual items from the OOBTree worked, when dereferencing the entire contents caused the traceback I posted (for example, even with a repr or in case of the traceback, when setstate() was being called while loading the object). > Some suggestions: > > - Figure out what the class of the object is and what the value of state is. > > - Try creating an instance outside your app and passing that state to > it to see if you get the same error. > Although the mapping has now been restored back to a sane state (by recreating another instance manually and replacing the original), I haven't yet figured out how it got to be in that state. I'll investigate further to see if there is a possibility of creating a reproducer. This might be a problem with karl's[1] CaseInsensitiveOOBTree (which is less likely since it is just a thin wrapper) or OOBTree.

OK, I have no idea what the problem is. It may be a ZODB bug, since, apparently, this showed up when you upgraded to ZODB 3.10.0b8, although I can't image what the bug could be. You're going to have to debug this, at least by whittling this down to a example that someone who doesn't have your software can run. Some suggestions: - Figure out what the class of the object is and what the value of state is. - Try creating an instance outside your app and passing that state to it to see if you get the same error.

What versions of Python are you using on the clients and on the server?
