I am seeing several failures on the Ubuntu 14.04 testbot, but unfortunately there are a number of changes that went in at the same time on that build. The failures I'm seeing are not appearing at all related to the test running infrastructure.
Anybody with a fast Linux system able to take a look to see what exactly is failing there? -Todd On Mon, Dec 14, 2015 at 1:39 PM, Todd Fiala <todd.fi...@gmail.com> wrote: > Hi all, > > I just put in the single-worker, low-load, follow-up test run pass in > r255543.
