Gatling场景在Windows上的高并发负载下似乎存在网络或HTTP损坏

我有一个非常简单的场景，它使用并发用户访问单个HTTP端点

当我以每秒10个请求的速度运行30秒时，一切都很好

当我在Windows上以每秒60个请求的速度运行30秒时，会出现非常奇怪的错误，在我看来，这些错误似乎是底层网络连接被破坏或被误用了。可能在Gatling或我的系统中的其他地方存在竞争条件或并发错误

我在linux机器上不会遇到同样的问题

web服务器是

nginx

和

PHP

。我不怀疑这是问题的原因，但我可能错了

如何跟踪并修复此错误

场景代码 症状 该场景报告了大约8%的失败率，错误看起来像是服务器正在使用格式错误的HTTP响应进行响应，返回HTTP状态行所在的HTML代码。这些细节各不相同，但以下是一个具有代表性的示例：
