System action
The warning message IEE822E has already been issued,
and the system deletes it now. Processing continues. Additional commands
are held in "waiting for execution" status, and will be executed as
current commands finish.
The system will delete this message
when the number of executing commands goes below 60% of the limit.
Operator response
Enter the CMDS DISPLAY command, and attempt
to diagnose the reason for the excessive number of commands.
Use
the CMDS SHOW and CMDS REMOVE commands to delete unwanted commands
before execution.
If necessary, cancel the job which is issuing
the excessive number of commands.
Notify the system programmer.
System programmer response
Diagnose the reasons for the excessive
number of commands. Possibilities include:
- A job or automation program got into a loop issuing commands.
- The commands which are executing have become hung, due to a resource
deadlock or a required action.
- The commands are legitimate; for example, a program has issued
VARY commands for a large number of devices.
