Tested and found on latest Beryllium.
After configuring a Netconf device on a clustered setup (see https://jenkins.opendaylight.org/sandbox/job/netconf-csit-3node-clustering-only-beryllium/ for a sandbox example) it is possible to write the configuration data exactly once. When an attempt to modify the data is subsequently made, weird things start to happen:
