I applied the fix mentioned before:
   in /etc/systemd/system.conf, 
   change
   #DefaultControllers=cpu
   into
   DefaultControllers=

I then removed myDaemon.service to start in SysV, and after
googing around, put this in my listener setup:
   int   optOn = 1;
   setsockopt(getHandle(),IPPROTO_IP,IP_FREEBIND,&optOn,sizeof(optOn))

It worked.  I now have myDaemon starting on boot, and
working correctly.

I am still hoping for additional information to get it
working correctly in systemd, as mentioned in other posts.

Thanks,
Mike.
