</div></div>This sounds like the network traffic between the cluster nodes and the<br>
remote nodes is being corrupted. Have there been any network changes<br>
lately? Switch/firewall/etc. equipment/settings? MTU?<br>
<br>
You could try using a packet sniffer such as wireshark to see if the<br>
traffic looks abnormal in some way. The payload is XML so it should be<br>
more or less readable.<br>
