With Boron-SR2, after I bring up my cluster or some instances are restarted in the cluster, I sometimes see that instances throw a IllegalStateException when I perform a writeTransaction to a container within a list where the key for the list is of type "inet:host". This works most of the times, but 1/10 runs I get this error for my periodic write operation?

Exact call:
-----------
modification.merge(logicalDatastoreType, iid, data, true);
