Java Chrome Selenium CI 测试随机挂起 3 小时

Question

我们的 CI Java-Chrome-Selenium 测试在套接字超时之前随机挂起 3 小时。我们得到错误:

挂起套接字/端口的低级调试消息是:

在非 fork 模式下运行 CI 测试时，我们用完了 PermGen 空间:

Caught an exception while logging the end of the build.  Exception was:
java.lang.OutOfMemoryError: PermGen space
java.lang.OutOfMemoryError: PermGen space
PermGen space

我们目前正在运行 JVM:

-XX:MaxPermSize=6144
-Xmx12288m

你可以试试 docker-selenium，这个想法是让 docker 运行一个容器，开始你的测试，然后销毁容器，这样就全部清理干净了
