    Description

      There are many different reasons why an app recovery could fail with an exception, causing the RM start to be aborted. If that happens the RM will fail to start. Presumably, the reason the RM is trying to do a recovery is that it's the standby trying to fill in for the active. Failing to come up defeats the purpose of the HA configuration. Instead of preventing the RM from starting, a failed app recovery should log an error and skip the application.
