(I was taking a nap at the time the buildworld crashed, we'll talk about that soon.) (Are you guys running with INVARIANTS?) So, I think we'll just include a warning with 4.9: WARNING! Do not attempt to stress a FreeBSD 4.9 machine if you: a) Will be swapping whatsoever or b) Will be taking a nap while it is running. Doing either or both of these may result in panics. Mike "Silby" Silbersack P.S. - now that we have an easy way to reproduce this, perhaps we can get it fixed.
