I have been using a 60 server 1560 brick 3.7.11 cluster without problems for 1 years. I did not see this problem with it. Note that this problem does not happen when I install packages & start glusterd & peer probe and create the volumes. But after glusterd restart. Also note that this still happens without any volumes. So it is not related with brick count I think...
