Whoops - in fact, this was the gist of my email to the lists, really; that someone might be interested in diagnostic information. The short answer: After not hearing a lot of interest in that - apart from your own response - and now having deleted the datasets in question: I hope so! I certainly do have the last crash dump - intact, as the machine hasn't crashed since...(...sound of knocking on wood) Pls tell me what debug info I can provide. The fix itself turned out to be quite easy, as you've indicated. My first concern was in being a good 'Listizen' - identifying/reporting on a bug, if one exists.

You should only see the errors continue if there's a dataset with a reference to the version of the file that creates those errors. I've seen this before: until all of the datasets are deleted, the errors will continue to be diagnosed, sometimes presented without databaset names, which might be considered a bug (it seems wrong that you don't get a dataset name for clones).
