I don't see timestamp but I guess you have a massive churn in the ip6_fib because of the deletion and immediate insertion of prefixes. > netlink receive error No buffer space available (105) netlink are sockets, too, and they can run out of receive buffer. Try ip -rc with a higher value then 1048576. Max value is /proc/sys/net/core/rmem_max/rmem_max (you can increase this, too). Thanks for the dumps, I will have a closer look later today.
