Symptoms

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%).

Impact

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.

Conditions

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

Workaround

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

Fix Information

None
