panic with ZERO_COPY_SOCKETS on 5.4 (and probably 6.0)
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. -- Best regards, Vadim Goncharov ICQ UIN 166852181 mailto:[EMAIL PROTECTED] ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

There were fixes for this after 6.0. I don't know if anyone is interested in merging the fixes to 5.5; you should update to 6.1 for this and many other reasons.

It sounds like the perfect way to spend some of the holidays ;) I've heard it won't run on a plain i386 out-of-the-box, what did you do to convince it to run? /Eirik Joshua Coombs ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable- [EMAIL PROTECTED] ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Ok, lemmie just point out that I'm already running 6.0, just to eliminate that issue. What I'm curious about is weather or not 6.0R's zero copy sockets are considered stable or not.

What I'm curious about is weather or not 6.0R's zero copy sockets are considered stable or not. Works for me[tm]. Cool, I'll have to give it a go then.
