I just recently installed SP4 and the hotfix that was listed after the upgrade (215906).
Now every job fails even on the SBE server itself. I've updated the Agent on all servers and rebooted all just to be safe. Still nothing. Jobs either fail outright or get missed and placed on hold. As soon as I release the job, they either fail or go into the eternal spin "queued" until it places itself on hold.
Also, now when I try to view the errors from the Backup and Restore tab by clicking on the specific server's error, it errors out with: "The server was unable to complete the requested operation. Unknown reason: 2 BEMSDK Failure Code: 2:X8 Error: 2: The job log for this job may not be generated." The only way I can view the log error is to go into the specific server and click on Active Alerts, then I can review the error messages.
