There are no global locks in kernel for entire routing table.
Wait, what?This must be the problem that I had earlier when I got strange error messages from Bird with the routing prefixes.
Since I disabled the SMP in all of the four machines that runs bird, I have not have this problem anymore.
As Pawel sad about this spikes, I see this as well when I run traceroute for example. Now I know where they are coming from.
