for whose who use HDDs put in kernel config setting below. makeoptions CONF_CFLAGS="-DBKVASIZE=32768" options MAXPHYS=4194304 or RAID5 arrays with large stripe size higher value of MAXPHYS would make sense. additionally bump vfs.hirunningspace and vfs.lorunningspace (in /boot/loader.conf or sysctl.conf) i have vfs.hirunningspace=50000000 vfs.lorunningspace=35000000 it should be at least few times MAXPHYS
