Can the other people running -current under high load turn on INVARIANTS and see if they start hitting the double free problems, too? I'd like some more evidence. Judging from the things we've seen from your traces I would guess at this point that there is a path somewhere that ends up in the ffs code without Giant, and that code fails to assert Giant requirements most of the time. Maybe it's time we start sprinkling the GIANT_REQUIREDs where we know they belong... that one we talked about adding the other day, did it catch anything? -- Bosko Milekic * bmilekic@technokratis.com * bmilekic@FreeBSD.org TECHNOkRATIS Consulting Services * http://www.technokratis.com/
