Hi, I've got a Squid/Lusca server on 8.0-RELEASE-p3 which is exhibiting some very strange behaviour.
After a few minutes uptime, the 4k mbuf cluster zone fills up and Squid/Lusca spends almost all of it's time sleeping in "keglimit". I've bumped kern.ipc.nmbclusters to 262144 and kern.ipc.jumbop to 32768 but the system will slowly crawl towards filling that zone. The box has a bce on-board NIC and is using ipfw to handle redirecting traffic to/from the box for transparent TCP interception. It's handling around ~30,000 concurrent connections at the moment. I have other very busy proxies on FreeBSD-7.x pushing a few hundred megabits without any issues. This box falls over after ~ 20 mbit. If I bypass redirection and/or kill squid, the 4k cluster count drops back down to < 500 and stays there. Does anyone have any ideas on where to begin debugging this? Thanks, Adrian _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
