We may be seeing a similar problem, or it could be something else entirely :-) We're using ip_fastfowarding, on a system routing 20k-30k packets per second between two intel pro/100+ cards. When we enable it, it causes strange system behaviour; System gets sluggish, pauses from time to time. It may be because IPFLOW_MAX is set to 256. We attempted to change it to 8192, but the system halts immediately after enabling fastforward. Can anyone advise how we can properly adjust varables in ip_flow.c? (IPFLOW_MAX, IPFLOW_HASHBITS, IPFLOW_HASHSIZE, IPFLOW_TIMER, etc). (We're using FreeBSD 3.4-STABLE, running BGP4 with 72,000 routes in kernel). Any help would be appreicated! ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
