I am also observing this kind of beahviour. But at a different level. We 
have an 8 node cluster composed of dual quad-core xeon. I have now updated 
all the nodes to RHEL 6.1, cman is at 3.0.12-41.el6.

and from time to time, for no apparent reason one random node has a peak in 
cpu usage, where it's corosync that eats CPU for a minute or so. During that 
time services on that node responds very slowly and ssh shell access is very 
rough and slow as hell...
