Attempted update my test server from 2.0.13 → 2.0.18 this afternoon. Achieved a ‘Passenger Physion’ failed state – could not reload dashboard.
Used ‘yum history undo’ to revert to 2.0.13. All is once again well with the test server.
Perhaps I should configure Passenger into the more verbose reporting state. Does anyone have a good reference to follow? Thanks.
