Node startup failed. Based on the stacks in __stacks.log, this looks like some kind of infra failure. I'll move this to test-eng, who may know more.

@herkolategan This is the mutex in NewDNSProviderWithExec,

return NewDNSProviderWithExec(func(cmd *exec.Cmd) ([]byte, error) {
		// Limit to one gcloud command at a time. At this time we are unsure if it's
		// safe to make concurrent calls to the `gcloud` CLI to mutate DNS records
		// in the same zone. We don't mutate the same record in parallel, but we do
		// mutate different records in the same zone. See: #122180 for more details.
		gcloudMu.Lock()
		defer gcloudMu.Unlock()
		return cmd.CombinedOutput()
	})

which contends with WipeForReuse, and causes the test to time out in the process. Did we hear back from GCE support on whether the global lock is required?

[herkolategan]

@srosenberg Thanks for the extra info, Renato and I were looking at this earlier. I'll create a support ticket; I planned to only create one if there were issues around the mutex, and unfortunately it doesn't seem to scale.

We have a support ticket open with Google https://console.cloud.google.com/support/cases/detail/v2/51236386?project=cockroach-shared.
