Duplicate lines in access log
I have found a duplicate line for EVERY request in my access.log (with the same time stamp) and cannot figure out why this is happening.i.e.
1.2.3.4 GET blah/blah 403 ...
1.2.3.4 GET blah/blah 403 ...
The relevant log entries in my httpd.conf are the following:
==============================================
LogFormat "%t %h \"%r\" %>s \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%t %{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
...
SetEnvIf Request_URI ".\.css$" dontlog
SetEnvIf Request_URI ".\.js$" dontlog
SetEnvIf Request_URI ".\.jpg$" dontlog
SetEnvIf Request_URI ".\.gif$" dontlog
SetEnvIf Request_URI ".\.ico$" dontlog
SetEnvIf Request_URI ".\.default$" dontlog
SetEnvIf User-Agent Googlebot dontlog
SetEnvIf Remote_Host "sv.av.com$" dontlog
CustomLog /var/log/access.log combined env=!dontlog
# rewrites to obscure robots.txt file from regular browsers.
RewriteCond %{HTTP_USER_AGENT} ^Mozilla
RewriteCond %{HTTP_USER_AGENT} !(Slurp¦surfsafely)
RewriteRule ^robots\.txt$ robots.html
==============================================
Any help would be mightily appreciated.
