A consistent hang calls for some deadlock.  Your configuration might be
tweaking some strange interoperation of functionalities that result in the
deadlock.  So, rather than the logs, the configuration would be of
paramount interest.  We are obviously looking for details, so don't omit
anything; rather sanitize sensitive information, like passwords.  I'm
specifically thinking about some strange interoperation between databases,
overlays, ACLs and so.
