Yes, it could be that the versions are out of step. I'm not sure about
what's in each of those versions as I don't recognise the numbers, there
were some incompatibilities between very old versions of cman and newer
ones. So I strongly recommend upgradeing .. or, at least using the same
version on all nodes.
