Not sure if there's anything that can be done about this but test-cluster-message crashed in CI on debian8-64:

Here's a crash on the same platform on a different test.

Both crashes were on test-digitalocean-debian8-x64-1 although I don't know if that's significant because I don't know that there are any other debian8-64 hosts.

This is the same root cause as #19903 and will be fixed by #20129. I'll close this out since we have a tracking issue already.
