and nothing came into httpd error message file ?
if it is something about timing that make httpd unable
to start then the error should be printed in error.log

if it something in cluster infrastructure
(rgmanager)...
never had happened to me, maybe in that case it is
some  old cluster.conf still active.

the "active" cluster.conf number is the same that it
is in the cluster.conf file?
manual change of that number and a forced propagation
of the new conf to the all cluster should fix that
