Might just be slow/overloaded machines taking more than 5s to Close a server? Perhaps we should just triple the timeout and see if the problem goes away.

bcmills · 2021-11-04T17:27:18Z

I'll be pretty surprised if that fixes it, but it at least seems worth trying!

Change https://go.dev/cl/476035 mentions this issue: net/http: remove more arbitrary timeouts from server tests

This change eliminates the easy, arbitrary timouts that should never happen. It leaves in place a couple of more complicated ones that will probably need retry loops for robustness. For #49336. For #36179.

This particular failure mode should be fixed by CL 476035. It is possible that that will uncover further failure modes, but watchflakes can file issues for those if they occur.
