104，由对等方重置连接。发送多个长http post请求时

Question

我有一个kubernetes集群（在GKE上），它运行tornado.web.Application服务器，在该集群上调用重载dask.distributed计算。 现在，我想测试我的服务器，并一次向它发送多个请求，看看它是否按应有的方式处理这些请求。 当我只发送一个请求时，无论请求有多大，它都会按预期执行所有操作和行为。 但当我发送多个请求时，大约5分钟后（我也尝试在服务器端睡眠，没有做任何计算，得到了相同的结果），我得到了以下结果：

所有请求都没有返回

如果没有这些错误，我如何获得所需的行为？ 我需要一个服务器，可以处理许多请求，并测试它从我的电脑
