Yes.

If that is your config than the start of the IP address on BOTH nodes is really 
bad. This should not happen and is definitely an error.

BUT: I doubt that this is you complete config, because this would not work 
anyway. The cluster would start the IP address on one node and the Webserver 
in the other node.

Please paste the complete config. Then the community would be able to help.
