Are you certain there is no issue with the web server? I have seen (years ago, prior to my use with haproxy) apache produce strange problems like this for ie that firefox was able to cope with if it's access_log file reached 2GB. On a busy server, that is easily reached in days or sooner, and typically it's only rotated weekly by default. Have you tried bypassing haproxy to whichever server(s) you are certain you are seeing the issue on?
