If you have time, can you see if the existing "--disable-sendfile" configure option gets rid of the bogosity too? If you're running code after 2.0.43, you can add "EnableSendfile Off" to your config for "<Directory />" to get the same effect. If we know if this does the trick, at least we have a work-around that doesn't require patches to Apache or APR. Presumably --disable-ipv6 isn't a good work-around :) Perhaps what is needed is --disable-ipv6-tcp-cork to no-op the socket option for IPv6 traffic only, since disabling it altogether is a performance problem for IPv4. If we knew what Linux kernels were broken* then this could be handled automatically at configure time, at least for those people not using binary builds. *assuming that it is Linux which is broken :) -- Jeff Trawick | [EMAIL PROTECTED] Born in Roswell... married an alien...
