If there are 3 managers and an error occurs in the 2nd just the first one will be recovered. This will leave the 3rd one untouched and thus the system in an inconsistent state. The manager that fails should also not be left running, I think we should call stop on that one. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
