full, dropped message
There were thousands of identical lines, all separated by a few
microseconds. No doubt this spew was the real cause of the apparent
interrupt storm and the resulting sluggishness.
I would imagine that if an interface is interupting that much then it's
constantly sending messages to route(4) to say that it's up/down and
addresses are detached/tentative in a tight loop. The queueing mechanism
has a fixed length and while we go out of our way to notify userland if
there's an error sending these messages, we can't send this one at all
so we just log it.
So it's an artifact of your interupt storm, but not the cause.
