When running config test; apachectl -t we get an error if the loadfactor is larger than 1. Our configuration works fine in 2.4.27, but fails in 2.4.28. Error received: > apache2 - AH00526: Syntax error on line 8 of config/workers.conf: BalancerMember LoadFactor must be a number between 1..100 Line 8 of config file in question: > BalancerMember URL:12000 route=admin loadfactor=100 status=-N If we change the loadcator to be between 0.0 and 1.0 it works in 2.4.28. We have found another reference to the same problem: https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fd.hatena.ne.jp%2Frougeref%2F&edit-text=&act=url Here's the merge with the change: https://github.com/apache/httpd/commit/52ae772654a0ab213bedad2e1bd38bebb80b245c
