@kevinearls do you know why these tests are failing to properly find open ports? Is there a bug somewhere in testutil.GetAvailablePort(t) that is the root cause that can be fixed?

[kevinearls]

@TylerHelmuth No, I don't really. I tried taking that approach but couldn't figure it out. Unfortunately I don't really have much more time to spend on this right now.

@kevinearls can you look into if getExclusionsList (which is used within GetAvailablePort) is not properly excluding all windows reserved ports. It is likely that there are some ports sneaking through the exclusion and they sometimes get chosen when they shouldn't. Try replacing "protocol=tcp" with "protocol=udp" or maybe adding "protocol=udp".

@kevinearls @TylerHelmuth I have a fix for the root problem, see #10872

@kevinearls thanks for your contribution, we merged the other PR that fixed the root cause.
