If you have different salt it implies that you have an enforcer running
at both nodes, or at least that the signconfs are not in sync. The
problem that you need to worry about here is what happens when one node
kicks off a key roll?

As has been said the salt change is not in itself an issue; but it would
indicate that the two nodes are not in step - which could be serious.
