Thanks for the tips. I am sure that none of the objects are loaded beforehand: I've got it localized to a run of unit tests that I can start afresh each time.
So far it's intermittent, seems to happen only one of say 10 runs. Happens more frequently on a fresh build of sample data for the test runs. The sample data build takes 45mins, so it's painful to run repeatedly. I'll see if I can wire up something that will loop on it overnight. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
