Symptoms

UDP flows continue to live till UDP idle time occurs, even after the subscriber is gone and the option for immediate deletion of the flow is enabled.

Impact

The UDP flows continue to be alive after the required time, but only act to drop the traffic.

Conditions

-- The option to delete flows upon subscriber deletion is enabled. -- The UDP flow is established with an idle time greater than the re-evaluate timeout.

Workaround

To work around this issue: 1. Modify the UDP idle timer to a suitable value. 2. Force delete the UDP flow from CLI.

Fix Information

UDP flows are now deleted after subscriber deletion.
