Symptoms

A source address persistence record created on a virtual server with a FastL4 profile times out and is aged out even while traffic is flowing through that flow. The traffic that results in this issue is UDP with checksum of 0.

Impact

Source address persistence is not usable as the entry ages out when it should not.

Conditions

The profile has to be FastL4. Traffic that is either UDP with checksum of 0, or SCTP, or ESP, are definitely affected.

Workaround

None.

Fix Information

Source address persistence record no longer times out unexpectedly on FastL4 profile virtual server.
