8606414334 HP-UX panics or hangs during NFS file copy over IPv4-in-IPv6 tunneling.

8606419996 Panic in tcp_reinit if the system has low memory and allocb fails.

8606437555 Incorrect checksum offload calculation on TOUR (HP-UX 11i v1 ONLY).

8606449326 The system keeps sending unnecessary ICMP dead gateway detection

packets when receiving the gratuitous arp packets.

8606450897 In TOUR 3.x, TCP connections can lose the ability to defer ACKs, resulting

in an ACK-only segment in response to every received segment.

sends an ICMP message with incorrect data type to TCP, that could panic

the system.

8606457119 TCP slow start after packet loss was broken. TOUR 3.x broke this feature

that was working in TOUR 2.X for HP-UX 11i v1, and was working in

HP-UX 11i v2 September 2004.

8606458794 The dead gateway detection patch is more resilient.
