I'm running a test three-node CS/GFS cluster. At random intervals I get the following kernel messages streaming out to /dev/console on all three nodes.

Are these messages related to CS/GFS? What triggers 'em? And should I worry about it?
I'm running Linux 2.6.9-34.ELsmp, GFS-kernel-smp-2.6.9-45, GFS-6.1.5-0 and dlm-kernel-smp-2.6.9-41.7.
