In your reports you said this was a very basic install and did not mention you changed parameters. Keep in mind for next time, when you mail a problem report, include all details you can. BTW you never run out of buckets, you can run out of entries, but that is a different sysctl variable. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
