I see the very same here on FreeBSD 10.0-CURRENT boxes (two boxes acting as NFSv4 server). The clients (all FBSD 10, one 9.1-STABLE) have two(!) identical mounts of the very same filesystem. /etc/fstab does contain the mount option "bg", but not "retrycnt=0". This behaviour happens on ALL FBSD 10.0-CURRENT boxes I administer (10.0-CURRENT #0 r250275: Sun May 5 18:40:17 CEST 2013 amd64). Regards, Oliver
