I tried modifying stop script adding 30 seconds sleep after killproc but the problem remains. Here is the stop script:

function stop() {
        # Stop daemons.
        prog=`basename ${slapd}`
        echo -n $"Stopping $prog: "
        killproc ${slapd}
        sleep 30
        RETVAL=$?
        echo
        if [ $RETVAL -eq 0 ]; then
            if grep -q "^replogfile" /etc/openldap/slapd.conf; then
                prog=`basename ${slurpd}`
                echo -n $"Stopping $prog: "
                killproc ${slurpd}
                sleep 30
                RETVAL=$?
                echo
            fi
        fi
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/ldap /var/run/slapd.args
        return $RETVAL
}
