Allbery KF8NH" To: freebsd-stable@freebsd.org Subject: Re: 4.3-S: No buffer space available [SOLVED: dummynet] Message-ID: <180940000.989362084@vpn38.ece.cmu.edu> X-Mailer: Mulberry/2.0.8 (Linux/x86) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I'm seeing this with mpd_netgraph from (< 1 week ago) ports running a PPTP tunnel. "top" claims there is 39M free; netstat -m similarly shows that I'm getting nowhere near any limits; yet periodically I see not only "No buffer space available" but also other misbehaviors such as dropped keystrokes in XFree86. Raising maxusers doesn't affect it. What may be significant is that I'm also running natd to support a host-only VMware setup (but VMware is not running when these problems occur); I'll be disabling that next. (The system runs fine with natd but no mpd, though.) The system has yet to panic as a result, so nothing useful from a debug session. Any other suggestions as to tracking this down? -- brandon s. allbery [os/2][linux][solaris][japh] allbery@kf8nh.apk.net system administrator [WAY too many hats] allbery@ece.cmu.edu electrical and computer engineering KF8NH carnegie mellon university ["better check the oblivious first" -ke6sls] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
