Jetty java.lang.NullPointerException处于高负载状态

我在jetty服务器v9.3上的5个qps负载上收到java.lang.NullPointerException

我定义了以下配置：

jetty.threadPool.maxThreads=500 jetty.http.acceptors=-1 jetty.http.selectors=-1

有人遇到过类似的问题吗

非常奇怪的NPE，因为这意味着请求对象本身是空的。实际上，您以某种方式让服务器处理一个不存在的请求。你能吗？我正在使用./wrk“server_address”-s scripts/post.lua-c 200-t 20-d 30m-R 15000我刚刚试过你的

wrk

选项，所有这些对我来说都很好。你能把你的服务器配置和你的

post.lua

粘贴到什么地方吗？谢谢添加了配置结果表明这是一个bug——它已在jetty-9.3.x分支中解决，并将在下一个9.3版本（下周）中出现
