Instance Method Details

#run ⇒ Object

The exception that we are handling can change in the case that the configured error proc raises an exception. If this occurs, the new exception will be passed to subsequent error procs. This is designed to avoid “hidden” errors, this way the daemon will log based on the last exception that occurred.
