【问题描述】：
环境：
- java-client(6.0.0-BETA4)
- 服务器 Appium (1.5.0)
- java 1.8
在自动化测试期间，在安卓模拟器上运行时，Appium 一直在我身上停滞不前。
由于似乎是服务器问题，很少有测试失败：
例外：
“org.openqa.selenium.WebDriverException：未知的服务器端错误 处理命令时发生。原始错误：无法停止 过程;它当前没有运行”
有没有已知的方法可以避免这个问题？
这是来自 Appium 服务器的更多堆栈跟踪：

使用“HOME”按钮退出应用时似乎失败了。
【问题讨论】：
-
那么问题是什么？
-
为什么会出现这个问题。以及如何避免。这种行为并非每次都可重现，而只是偶尔重现。我的问题是如何避免这种情况。
-
使用此信息更新主要问题以进行正确分析
-
你能添加更多关于拆卸功能的细节并分享堆栈跟踪吗？您是否并行运行 2 台设备？
-
Teardown 函数被覆盖方法 afterInvocation() 和 stacktrace 在上面。但是认为我已经找到了问题，当 OverrideSession 参数设置为打开时，这是服务器中的一个错误。仍在测试这是否会重新出现，但如果不是 100%，这将是问题。
