Too many jobs are running that use the communications controller.

Before you can run your communications job, you must do one or more of the following:

• End any diagnostic program that may be running, such as the Communications Trace Program.
• Vary off a line that is using the controller.
• Lower the speed of a line that uses the controller.

Perform the following to find which lines are using the controller:

1. Vary off the failing line using the VRYCFG command.
2. Vary the line on again, with the reset option of the VRYCFG command set to Yes. The names of the lines using the controller will be displayed.

This ends the procedure.
