Bummer!
I went through the last commits of tail, but at first glance I didn't see anything that might be related to this issue.
It could also be because changes that came in with notify 5.0.0-pre.16, or notify 5.0.0

I haven't noticed this test being flakey for a while now, is it still failing intermittently, or can we close the case safely ?

Looks like a different error message but just had a failure from test_retry9 on my PR #7492
