What do the stats look like on the receiver? Also, 'netstat -di' would be useful since it shows drops due to no buffers available. >77 mbufs in use: > 65 mbufs allocated to data > 5 mbufs allocated to packet headers > 6 mbufs allocated to protocol control blocks > 1 mbufs allocated to socket names and addresses >64/128 mbuf clusters in use ...looks fine. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
