Running some iterations locally to see if I can make this fail.

There haven't been any hits here. But that could be due to the duplicated messages not matching the error pattern we used here.

@mitchdenny should this be closed?

[mitchdenny]

I haven't seen it for a while. I think we can close. We can always reopen if we spot it again.
