我有一个节点API,通常可以很好地处理流量。但是,在我们的高峰时期,它进入这种状态,它开始使用100%CPU并需要重新启动。重新启动后,它会在接下来的几天内恢复正常状态。
使用负载测试网站,我已经能够重现此问题。我负载测试的请求非常简单,所以我担心问题出在我正在使用的第三方库中。
我是调试节点的新手,我不知道如何从node-tick-processor输出以下内容。任何人都可以破译这个吗?
更新:我正在运行节点v0.10.4

对于那些仍然来到这里的人来说,这是由系统节点模块中的SSL处理代码引起的。我重新配置我的堆栈以在nginx上执行SSL终止,并在节点级别使用基本的HTTP处理,这个问题完全消失了。
