@prattmic, that list is slightly overmatched. The oldest three -race failures were #56118, I think.

But it's close. The ones since Oct. 18 are mostly (or all?) this failure mode:

Intriguingly, all of those failures are on either freebsd or darwin, and parts of the Darwin platform (notably the network stack) are derived from FreeBSD.

Could be a (presumably very old) kernel or libc bug, or some other difference in the net stack where FreeBSD and macOS don't satisfy some assumption that happens to hold elsewhere.

Looking at both of these outputs:

There seem to be another test running in parallel which opens several client TLS connections in the same port sequence range. Maybe it "hits" the non TLS server of TestTransportMaxIdleConns, causing it to be marked broken?
First log is missing "|http|host-0.dns-is-faked.golang:17796" .

2022/11/18 11:44:36 http: TLS handshake error from 127.0.0.1:17704: read tcp 127.0.0.1:17702->127.0.0.1:17704: read: connection reset by peer

The second log is missing "|http|host-4.dns-is-faked.golang:30467" for the evict case.

2022/11/05 13:12:35 http: TLS handshake error from 127.0.0.1:30346: write tcp 127.0.0.1:30337->127.0.0.1:30346: use of closed network connection

There seem to be another test running in parallel which opens several client TLS connections in the same port sequence range.

I fixed one such test in https://go.dev/cl/476036, but I suspect there may be others remaining.
