It's known problem: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/67919 And there is bandaid patch by Uwe Doering that at least allows to keep system alive: http://freebsd.rambler.ru/bsdmail/freebsd-stable_2004/msg03698.html I'd applied this patch year ago on one of our production servers, and the bug was gone. However, no one wants to commit this patch. Igor Sysoev http://sysoev.ru/en/
