No that's fine, I run several machines with maxusers at 512 and NMBCLUSTERS at 32768 (although the ram is usually at 512 to a 1024), let me know if you have any problems with those settings though as I'd like to know if they are set too high for heavy load. I would also suggest using fxp cards (Intel Ether Express Pro) in the future, they are definetly my favorite. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
