> The SetDataTxn contains the client data + a couple extra fields. On ingest
> the server is applying the jute.maxbuffer size to the data (expected) but not
> handling the fact that the data plus these extra fields may exceed the
> jute.maxbuffer check when reading from disk.
> Workaround was simple here: set the jute.maxbuffer size a bit higher (and fix
> the mis-behaving client, expectation was not that the data would grow this
> large).
