Removing ZERO_COPY_SOCKETS from kernel config resolved problem. And I've found same diagnostic with same causes in freebsd-current@ mail lists on a 6.0-RC1: http://www.freebsd.org/cgi/getmsg.cgi?fetch=330124+334658+/usr/local/www/db/text/2005/freebsd-current/20051023.freebsd-current Also, there is a PR with a similar diagnostic (but not sure if it is ZERO_COPY_SOCKETS problem): http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/75780 I still have coredumps on my machine together with copy of kernel.debug (although I've updated machine to 5.5-PRERELEASE alredy), and can provide backtrace etc. if somebody will be interested in this. -- Best regards, Vadim Goncharov ICQ UIN 166852181 mailto:vadim_nuclight@mail.ru
