So you really *are* out of mbufs. What network driver are you using?
Maybe it leaks.

Delay a little first maybe -- or you might make it worse. But the case
where you get ENOBUFS when trying to increase the socket buffer size is
usually caused by hitting the relevant limit; the right thing to do is
to request a little less space until you get what you asked for.
