Out of curiosity - What Software version is in use ?
Do you have a tcpdump "client side" that shows the packets going into the F5, and a corresponding one showing nothing going out ?
Is there anything strange about the DNS responses going outbound, could they have been truncated and an upstream firewall not allowing a TCP response ?
