When handling UDP traffic on a FastL4 VIP, sometimes the TMM tries to offload both client and server flow when there is only one way traffic (either client-side or server-side). That would result TMM crashed on invalid pointer access.
Traffic disrupted while tmm restarts.
HSBe2 platform, FastL4 VIP for UDP traffic, and one-way traffic during run time.
This issue has no workaround at this time.
TMM now handles one way UDP traffic offloading correctly.
