S-522 -- the horror (for Operations)

A 522 Completion Code indicates that the System was in a Wait State. Whenever a command or request is made by the Operating System, and a response is not forthcoming within 30 minutes, the job is automatically terminated with a 522 Storage Dump. The most probable causes are:

• Operator missed Mount Request message.
• Operator failed to respond to other System requests.
• Invalid User Request.
• Operating System error.

A check with the installation and computer operations should be made to determine specific problem causing the Wait State.

I remember TJ (see the Halloween pic with Mac), who had a knack for sleeping while standing up against the tape drives, and the console cranking out Mount Request messages. The horror! ...

Good times.
