Autorelease since October 20th has been consistently failing at various places in the build. Often SingleFeatureTests appear to just crash and build cancels. This seems to be the most common issue. There's also the issue we've seen related to Connection Refused as well but that's likely another issue related to Nexus that we should investigate separately.
