See: https://issues.apache.org/bugzilla/show_bug.cgi?id=45950 https://issues.apache.org/bugzilla/show_bug.cgi?id=39811 https://issues.apache.org/bugzilla/show_bug.cgi?id=44736 https://issues.apache.org/bugzilla/show_bug.cgi?id=42621 The one that really hit us is that if you have a config with 5 balancers set up in this order in the config - [ a, b, c, d, e ] - and then introduce another 2 balancers into the configuration file so they are in this order [ a, b, f, g, c, d, e ], and then do a graceful restart, then the state of c and d get applied to f and g. Plus, of course, if you do a full restart you fall back to whatever configuration is in the config file, meaning if someone has manually disabled/enabled any balancer members that info is lost. The proxy balancer stuff certainly does not work as well as it could.
