Our TravisCI builds consistent take at least 40 minutes to complete. TravisCI kills a build after 50 minutes, which we periodically hit and causes the build to fail. This makes it difficult to validate the pull requests didn't break anything.
We need to figure out a way to make our builds take less time. Maybe we can disable a few long runing tests that aren't actually that important, or maybe change our TravisCI matrix to just build certain tests on each matrix.
