Subject Re: [users@httpd] Apache on CentOS 6 -- lots of reading requests
Date Sat, 06 Apr 2013 08:24:38 GMT

i had the same problem after migrating from Centos 5. After a few days of
testing, reinstallations between Centos 5 and 6 and recompiling different
kernels i found it.
It is connected with Preconnection function in new browsers ( and starts
showing in kernel 2.6.32.
Probably previous kernels including are handling such requests in
different way and they doesn't come to Apache until http header is sent.
I do not know what exactly has been changed between and 2.6.32
(changelog is over 8MB long) but it seems to be ok that Reading Request
connections appear in server status.
If you have too many of them you can decrease Timeout in httpd config.
