I have been hit by these failures as well. I think you did well by bumping out that revert from the queue; I think it simply cures the sympton possibly affecting correct operations of the firewall service. If we are looking at removing the sympton on the API job, than I'd skip the failing tests while somebody figures out what's going on (unless the team decides that it is better to revert again multiple workers). However, I think the issue might not be limited at firewall. I've seen a worrying spike in rally failures [1]. Since it's non-voting probably developers do not care a lot about it, but it provides very useful insights. I am looking at rally logs now - at the moment I have not yet a clear idea of the root cause of such failures.
