I do not think load on network was any higher than usual for this system (max 700mbit/sec of inbound video multicast on same interface) Both nodes saw same error and was running same kernel.
After reboot, the messages went away. tipc-config was ran right before this, by a script trying to set network ID and tipc addresses. This would have failed as the links were already configured. (And no we have not yet switched to use “ip tipc” command, as we have to still work on some older kernels too).

When we have seen this before it has normally been an indication that the (very short) link monitoring messages still go through, and that there is something wrong with the packet being retransmitted. It cannot be the MTU, since the first packet is only 265 bytes long, and as far as I can see the source address is also ok. Are you running the same kernel version on node 1.1.2? Do you have high load on on the network when this happens? If it is repeatable, maybe you could provide a wireshark dump?
