Would you have logs of your builds, so that I could check whether there is any surprising diff (apart from the test failure)? Meanwhile I'll downgrade the severity as a) it seems like a system-specific issue and b) in the specific context a very small positive number likely doesn't break applications. > Are able to reproduce this failure at will? > I will investigate - my build slaves will be very busy for several more hours, but once they've calmed down I will re-try!
