Thanks to all who replied. The problem as was pointed out on the list and  
as I suspected was in the ssl conf file which couldn't be loaded into 
both instances because of the conflicting ssl port 443. So what I did was 
duplicate the conf.d directory for config-2 and change the ssl port and 
then load the different cond.d directories into the two instances.

Thanks,

Tony
