二、你期待的结果是什么?实际看到的又是什么?
三、你正在使用的是什么产品,什么版本?在什么操作系统上?
四、请提供详细的错误堆栈信息,这很重要。
五、若有更多详细信息,请在下面提供。

没有用的
hystrix-metrics-event-stream1.5.18版本的源码HystrixSampleSseServlet.java
问题导致的原因就是:observeOn(Schedulers.io())开辟了子线程对监控数据做打印,主线程while循环里面打印ping, 两个线程中都有对同一个writer做writer.print()和writer.checkError()操作, 不同线程操作导致了输出Buffer异常,master分支上的代码解决方案其实就是添加一把同步锁synchronized (responseWriteLock)。
