The restart_dirsrv script wasn't initializing the api so the startup_timeout wasn't available. The subsystemCert cert-pki-ca definition was missing so we didn't know which certificate to update in CS.cfg. Add some documentation and a pause between restarts for the renew_ca_cert script so that when the CA subsystem certs are renewed they don't all try to restart the CA at the same time. https://fedorahosted.org/freeipa/ticket/3006
