The subscriber can not be added with the same IP address after retries. This is a rarely occurring issue: if the daily average of subscriber additions is ~30000 subscribers, 5 to 6 subscribers face this problem (0.02%).


Intermittently (a few operations per day), the command silently fails. No session is created, and no TCL error is produced. Subscriber addition requires manual intervention.


Running iRule to create PEM sessions from RADIUS packets using the 'PEM::subscriber create' command.


Trigger a RADIUS START using a different IP address for the subscriber.
