A couple of thoughts: - Could you try again with the latest bzr head? Or perhaps with 3.0b3 which I'll be releasing soon? You'll have to switch to Python 2.7 though. - I'm seeing lots of errors in HyperKitty before the database locked error. I wonder if one of those errors is causing a transaction to stay open too long? If one process gets the error and doesn't abort the current transaction, it'll cause this database lock error in another process. Because of the way Storm is used, just about anything, including reading data, will open a transaction (you see this often in REST test cases). - Perhaps you can disable HyperKitty and run your tests again? -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1091586 Title: Frequent OperationalError: database is locked with sqlite To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1091586/+subscriptions
