Kubernetes Replication Controller集成测试失败

Question

我看到以下kubernetes集成测试总是失败，在RHEL 7.2、Fedora 24和CentOS7.1上大约90%的时间都会失败：

test/integration/garbagecollector
test/integration/replicationcontroller

它们似乎是由于etcd故障造成的。我的在线查询使我相信这可能还包含一个apiserver问题。我的设置很简单，我安装/启动docker，安装go，从github克隆kubernetes存储库，从存储库使用hack/ install -etcd.sh并将其添加到path，获取ginkgo、gomega和go-bindata，然后运行'make test-integration‘。我不会手动更改任何内容或添加任何自定义文件/配置。有没有人遇到这些问题并知道解决方案？我在网上看到的关于这个问题的唯一提到被认为是一个薄片，没有列出的解决方案，但我几乎每次测试运行都会遇到这个问题。下面是错误的部分，如果需要，我可以给出更多：

垃圾收集器：

提前感谢！

我增加了对文件描述符数量的限制，从那以后就再也没有遇到过这个问题。所以，我要说这件事已经解决了
