well, heres the relevant part of my config file
        <rm>
                <failoverdomains>
                        <failoverdomain name="httpd" ordered="1" restricted="1">
                                <failoverdomainnode name="tf1" priority="1"/>
                                <failoverdomainnode name="tf2" priority="2"/>
                        </failoverdomain>
                </failoverdomains>
                <resources>
                        <script file="/etc/init.d/httpd" name="cluster_apache"/>
                        <ip address="192.168.1.7" monitor_link="1"/>
                        <script file="/etc/init.d/postfix" name="cluster_posstfix"/>
                </resources>
                <service autostart="1" domain="httpd" name="Apache Service">
                        <ip ref="192.168.1.7"/>
                        <script ref="cluster_apache"/>
                </service>
                <service autostart="1" domain="httpd" name="postfix service">
                        <ip ref="192.168.1.7"/>
                        <script ref="cluster_posstfix"/>
                </service>
        </rm>

ive never seen that ssl error when starting the service manually.


the other thing that I noticed.. is that when I try to do 

[root at tf1 cluster]# clusvcadm -d "Apache Service"
Member tf1 disabling Apache Service...

it just hangs there and never returns.
