Thanks for your response Jeffrey.  So, if I want to try the limit
method, would the recommended procedure be to change the init 
script to read:

if [ -x /usr/afs/bin/bosserver ]; then
        ulimit -H -n 1024
        echo "Starting AFS Server processes"
        /usr/afs/bin/bosserver &
        OPTIONS="$OPTIONS -nosettime"
        sleep 30

This would affect more than the fileserver.
