It looks like the problem is here:

+ eval ' limits -C daemon   /usr/sbin/ntpd  -p /var/db/ntp/ntpd.pid -c 
/etc/ntp.conf  -u ntpd:ntpd'
+ limits -C daemon /usr/sbin/ntpd -p /var/db/ntp/ntpd.pid -c 
/etc/ntp.conf -u ntpd:ntpd
daemon control: got EOF
+ _return=255
+ umask 0022
+ [ 255 -ne 0 ]
+ [ -z '' ]
+ return 1
+ warn 'failed to start ntpd'
