Intermittent org.openqa.selenium.remote.UnreachableBrowserException:

Hello,

When running through some testing using Appium, the server seems to crash mid-test. This does not always happen, and is intermittent. But with longer test suites, it is starting to become more frequent. We’re using the latest Appium (1.6.1 Beta) and were holding out for hope. We’ve been seeing this since the previous version.

Any information on what causes this, or how to prevent it? Right now we try to restart our server after each device, so tests only fail on one device.
