Hello,
I have a similar issue with Appium 1.6.4-beta.
We run our iOS tests nightly for almost 7 hours and at some point (during the last 1-2 hours) we kick off a new Appium instance on a different port to run the Android tests, and they overlap for almost 1 - 2 hours.
The issue is that the iOS tests crash some time after the Android tests start with the following stack trace:
[debug] [MJSONWP] Calling AppiumDriver.timeouts() with args: ["implicit",1000,"01227913-2361-48fb-a16b-98cbaa73266b"]
[debug] [XCUITest] Executing command 'timeouts'

If I run a subset of them locally, they run in parallel without any issues.
The interesting part is that on the Continuous Integration server, even though the iOS ones crash, the Android ones keep running just fine.
I have also replied to this GitHub issue but I didn’t see any activity on it: https://github.com/appium/appium/issues/2571
Any ideas how I could fix this?
Thank you!
