If the BalancerMember directive contains a URL with a hostname longer than X characters, we fail as follows: BalancerMember worker hostname (65.character.host.name) too long The same fix for https://bz.apache.org/bugzilla/show_bug.cgi?id=53218 on the worker name needs to be applied to the hostname, and separately the size of the hostname needs to be raised so it is RFC1035 compliant in trunk.
