I believe we've seen this same error on other Event Log tests - and apparently retries aren't a reliable workaround. I wonder whether we need an attribute for a category of tests that we cannot make more than 99.9% reliable and (unlike networking tests perhaps) we also believe we are very unlikely to break. Such tests we would run manually before releases.

That sounds like a better approach going forward. Other tests already failed again: https://dnceng.visualstudio.com/public/_build/results?buildId=525306&view=ms.vss-test-web.build-test-results-tab&runId=16620540&resultId=180692&paneView=debug.

So I would disable all EventLog tests on CI by attributing them with a custom trait (we already have one called IgnoreForCI).

Let's do that.
