(3.0-current) Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I've been having similar issues that where mentioned here yesterday by somebody. I've been racking my brain trying to figure out why my 3.0-current box has been unable to telnet to my USR TC racks. I get the connected message, and then nothing. tcpdump shows similar activity to what's been posted. I traced it to a sysctl I had in /etc/rc.local that bumped the tcp recvspace to 65536. Resetting it to the default clears the problem up. So there's a bad interaction in there somewhere.
