However there are no diagnostic messages set for > the application indicating that the application failed because of expiration. > Even if the AM logs are examined, it's often not obvious that the > application was externally killed. The only evidence of what happened to the > application is currently in the RM logs, and those are often not accessible > by users. -- This message is automatically generated by JIRA.
