I was able to make it out of that issue with listings by recreating everything on 3.12.X Or maybe it was some setting conflict as I ran tests of each setting for performance and left only those that gave better results. End up with settings below for the distributed mail-server using maildir cluster.readdir-optimize didn't do much anyway
