Yes, I have!
Solved by doing the following

yum upgrade pacemaker pacemaker-libs
gave me a working crmd on 1.1.3

cibadmin --modify --crm_xml '<cib crm_feature_set="3.0.1"/>'
set feature_set to 3.0.1, I had to look at the code to realize that this is
the cause of the problem.
The log line "We can support up to CRM feature set 3.0.2 (current=3.0.1)"
is a bit confusing and makes you to think the feature set version is not the
issue here

heartbeat stop

yum downgrade pacemaker-1.0.9.1-1.15.el5 pacemaker-libs-1.0.9.1-1.15.el5
pacemaker-debuginfo-1.0.9.1-1.15.el5

heartbeat start

and everything is fine again !

Cheers,
Pavlos
