@ochubey ok, I give the log when running ios_webkit_debug_proxy, It’s all ok:

➜  appiumlog ios_webkit_debug_proxy
Listing devices on :9221
Connected :9223 to test的 iPhone (ed1ecf1e2ddd960ec5acac87da88a38b387cca15)

And I know that ios_webkit_debug_proxy won’t be triggered by appium server start, But the java_client(5.0.0BETA9) has the capability capabilities.setCapability("startIWDP", true) to start the iwdp automated. If you think that Jenkins might have its own environment, I understand you. however, when I use JSch or Ganymed SSH-2 by java to ssh the remote server and start the appium, then I excute the ios test .(the device is connected to the remote server and the test script is also on the remote server ) It was still crashed. Can you see what I mean?
