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.
Source address persistence is not usable as the entry ages out when it should not.
The profile has to be FastL4. Traffic that is either UDP with checksum of 0, or SCTP, or ESP, are definitely affected.
None.
Source address persistence record no longer times out unexpectedly on FastL4 profile virtual server.
