The system has detected a shortage of non-system extended LXs.
Notify the system programmer.
Determine if the number of non-system extended LXs is too small, or if an application problem is causing non-system extended LXs to be orphaned. There is a limit of 30,720 extended LXs, which includes both system and non-system extended LXs. Decreasing the number of system extended LXs will increase the number of non-system extended LXs that are available, but might cause message IEA070E to occur.
