Thank you for your response. Unfortunately, I cannot bring a node
down unless I have a full game plan. If anyone can provide some
insight, that would be great. I have a feeling that rebooting the
cluster would bring things back to normal but would like to understand
possible root causes and perhaps a way to fix it without rebooting.
