EQA1673W An attempt to automatically restore an AT breakpoint type breakpoint failed.

Explanation

z/OS® Debugger was attempting to restore a breakpoint that had been set in the previous process and has failed in that attempt. There are two reasons this could have happened. If the Compile Unit (CU) has been changed (that is, modified and recompiled/linked) between one process and the next or a breakpoint had been established for a statement or variable that no longer exists due to the change, when z/OS Debugger attempts to reestablish that breakpoint, it will fail with this message.
