start up scripts stopped working

[Eric]

hello,

does anyone know what I can do to fix the following problem?  Every time 
my FreeBSd 6.2 machine reboots, none of the scripts in the 
/usr/local/etc/rc.d directory launch the various programs i have defined 
in my rc.conf file. when i added

rc_info=yes
rc_debug=yes

to rc.conf i see things getting evaluated, but nothing is launched. this 
forces someone to log in locally to the machine and start openssh so i 
can get to the box.

does anyone know what could be causing this?
