Description (partial)

Data plane ucode crash is caused by the half open list being corrupted

The corruption occurs because the firewall session is added to the half open list more than once. The conditions to recreate this issue are extremely difficult to reproduce. This is primarily a UDP issue since it does not provide any state like TCP does.
