* Stefan Fritsch s...@sfritsch.de: This is a rather strange bug: - It happens if I enable exactly two out of the three modules deflate, reqtimeout, dump_io. But not with only one or all three of them. - I have also tried replacing mod_ssl.so, mod_deflate.so, and the openssl-libs with the versions from karmic and mod_ssl.so with the version from jaunty: no change But the bug disappears if I do mv /lib/i686 /lib/disabled_i686 Confirmed. I deinstalled libc6-i686 and the error is gone! There was a bug recently in Debian related to some gcc versions creating wrong code for SSE4. Maybe that is the problem here, too.

* Stefan Fritsch s...@sfritsch.de: I suspect this is the same issue as bug #595855 and #595116: Headers are getting truncated with https. So far, I have no idea about the reason. If you have mod_reqtimeout and/or mod_deflate enabled, you can try if disabling one or both of them makes any difference. disabling mod_deflate does indeed make it go away. -- client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23) https://bugs.launchpad.net/bugs/589611 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

* Thierry Carrez thierry.car...@ubuntu.com: It's definitely a client-side issue, however before your upgrade your Apache configuration would just accept those broken requests without error. In particular, IE6/7 are knows for broken HTTP/1.1 handling. I wonder what changes you applied to your Apache configuration. In particular, did you use to have BrowserMatch directives that you didn't carry through your upgrade ? I have now enabled these: # Netscape 4.x has some problems... BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html which were disabled BEFORE the upgrade. It's quite odd. I could disable them now to see if the problem reappears. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de -- client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23) https://bugs.launchpad.net/bugs/589611 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
