Probably a question for TAC, but I thought I would ask the group mind.
I am seeing a bunch of the messages "kernel: [fw4_0];skbuff_packet_fragment: No need to fragment!" along with a bunch of "last messages repeated x times." This is a VPN server attached via Maestro (r81.10) with another member. The other member is doing it too. And the other VPN devices on the other side of the US in another data center are doing it too.
Would not have noticed it except we were troubleshooting some else's problem (because it is always the firewall of course.) Saw that message start last night, but found it had been in the other site since June.
