appium: Appium 1.7.1 is stuck at [JSONWP Proxy] Proxying [POST /session] to [POST http://localhost:8100/session] with body: {"desiredCapabilities"

The problem

When upgraded into Appium 1.7.1, everytime app started by Appium in Simulator , I need to wait 2~6 mins to let test run. After check the Appium log, I found Appium paused at:

[debug] [JSONWP Proxy] Proxying [POST /session] to [POST http://localhost:8100/session] with body: {"desiredCapabilities":{"bundleId":"com.***.****","arguments":[],"environment":{},"shouldWaitForQuiescence":true,"shouldUseTestManagerForVisibilityDetection":false,"maxTypingFrequency":60,"shouldUseSingletonTestManager":true}}

after 6 mins, Appium get the following, and start to run

[debug] [JSONWP Proxy] Got response with status 200: {"value":{"sessionId":"396FCBB1-11DE-4C6D-8A07-751C97CEB2DC","capabilities":{"device":"iphone","browserName":null,"sdkVersion":"11.1","CFBundleIdentifier":null}},"sessionId":"396FCBB1-11DE-4C6D-8A07-751C97CEB2DC","status":0}

Environment

• Appium version (or git revision) that exhibits the issue: 1.7.0, 1.7.1
• Last Appium version that did not exhibit the issue (if applicable): 1.6.5 (no issues)
• Desktop OS/version used to run Appium: Mac OS 10.12.6
• Node.js version (unless using Appium.app|exe): v7.10.0
• Mobile platform/version under test: iOS 11.0, 11.1, 10.3.1
• Real device or emulator/simulator: simulator
• Appium CLI or Appium.app|exe: CLI
• Xcode version: 9.0, 9.1

Details

Currently, after app launched, I always need to wait 2~6 mins to let Appium responded, and start to run my test…

Appium 1.6.5 can run it without any issue. I think it should be introduced by 1.7.0 and after.

https://github.com/appium/appium/issues/9482 has the same issue, although the issue has been closed, she reproduced it again recently, cannot find a solution.

Great thanks!!
