The Hybserv Services project has abandoned development long time ago, as they also have mentioned on their github project's site. So basically HybServHybserv is outdated and the protocol is no longer compatible with modern ircd-hybrid.
From what I have read on www.ircd-hybrid.orgwww.ircd-hybrid.org, the Anope IRC services is the recommended ircIRC services package for use with ircd-hybrid.
