AEDF
Explanation
CICS has suspended the user task to allow the EDF task to complete. The user task has been purged while suspended, before control was returned from EDF.
System action
The task is abnormally terminated with a CICS transaction dump.
User response
The task was probably purged by the master terminal operator.
Investigate the reason why the task was purged. This may have been in an attempt to clear the system which appeared to be deadlocked for some reason.
