I tried them and they give a very accurate picture of tcp/ip usage of mbufs. Unfortunately, it shows the same results as netstat - around 100 mbufs in use. However, netstat -m shows almot 10K in use. One of the tools shows the contents of the mbufs and many are completely nulls and others are obviously left over buffers as they have log file contents from weeks ago. What besides tcp/ip uses mbufs? Can mbufs become orphaned? -- -- Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
