Not sure what might cause it.  Assuming you have 5.1[.z] installed:

(a) install matching -debuginfo RPM
(b) killall -USR1 clurgmgrd

Then attach /tmp/rgmanager-dump

Also, note that you can't run 'clustat' as non-root, and there's a
chance SELinux is preventing creation of the rgmanager admin socket.
