See original GitHub issueI was playing wtih long-running tasks with Distributed Dask scaling a number of workers up and down, so I’m not exactly sure what actions led to the hanging Distributed master with the following log:

@mrocklin I will sure be able to run the fixed version. Let me know once you have it. These types of bugs are really nasty, so it will be nice to have detailed logging there, so we can see whether we could have had the state in which it failed previously.
