</div>This is entirely consistent with a network interruption.<br>

</div>The most likely explanation for what you saw is a network interruption.<br>
If clustered nodes are not able to communicate for some period (about a<br>
minute by default) then the cluster will break. Rabbit clusters do not<br>
cope well in such environments. You should use federation or the shovel<br>
instead if you have poor network reliability:<br>
