Hello freebsd-stable,
I've seen several panics on a 5.4-STABLE (RELENG_5 at end of January)
under moderate ftpd/samba load with diagnostic:
vm_page_free: freeing wired page
Server rebooted after a panic every ~4 hours. 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.
