Comment 3 for bug 143593

I only marked this as "incomplete" as it lacks any information that could be used to track down the problem. All cases of the "Shouldn't load state for ..." message I've seen were caused by application code. Like storing persistent objects in module scope variables, on the request or any other inappropriate places. Or sometimes by accessing persistent objects after the db connection was indeed closed, like sometimes in EndRequestEvent handlers or those request._held hooks.
