My guess is there is a corruption in vol list or peer list which has lead
glusterd to get into a infinite loop of traversing a peer/volume list and
CPU to hog up. Again this is a guess and I've not got a chance to take a
detail look at the logs and the strace output.
I believe if you get to reboot the node again the problem will disappear.
