Did you rule out an IP collision with the 10.1.4.115 address? If you've configured a self-ip on 10.1.4.0/24 and you can't see any of the L2 adjacent systems it sounds to me like you may have had some arp confusion. I say this because I noticed that you've got a system on an adjacent IP address (.116).

 

 

It may be helpful to see what is going on arp-wise, so try running "tcpdump -ni internal arp" with your self-ip configured.
