running 3.3 distributed on IPoIB on 4 nodes, 1 brick per node. Any idea why, on one of those nodes, glusterfsd would go berserk, running up to 370% CPU and driving load to >30 (file performance on the clients slows to a crawl). While very slow, it continued to serve out files. This is the second time this has happened in about a week. I had turned on the gluster nfs services, but wasn't using it when this happened. It's now off. kill -HUP did nothing to either glusterd or glusterfsd, so I had to kill both and restart glusterd. That solved the overload on glusterfsd and performance is back to near normal. I'm now doing a rebalance/fix-layout which is running as expected, but will take the weekend to complete. I did notice that the affected node (pbs3) has more files than the others, tho I'm not sure that this is significant.
