Hi,
It seem to be problem with network traffic.
Have you tried to sniff network traffic to be sure that udp traffic reaches
from one node to another ??
Try on server1:
tcpdump -i interface -p udp -s 192.168.100.112
on server2:
tcpdump -i interface -p udp -s 192.168.100.111
if there will be no packet traffic, that means you have some network issue.
BTW: Is SELinux enabled on nodes ??
