Beats the heck out of me, but it happens constantly on my laptop when I'm using the VPN (mpd; dynamic addresses mean I can't use IPSEC). Also, it constantly loses loopback packets. Usually it recovers by itself after a minute or so. I've tried fiddling with everything I can find and am considering instrumenting the kernel to syslog a stack trace any time something wants to return ENOBUFS. It's really annoying. I also see similar problems on the machine which is my PPP router / NAT gateway. -- 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-isp" in the body of the message
