我的JMeter在一个有2个内核和512m内存的Docker容器中运行。jmx文件设置有10个并发用户，没有启动时间，测试时间设置为5分钟。我在一个微服务上反复运行这些测试，该微服务对10000个整数列表进行合并排序，以查看不同JVM参数的延迟差异。该微服务还运行在Docker容器上，该容器有2个内核和512m内存。我以前用1000整数列表执行过这个测试，没有遇到任何问题，但当我将整数列表设置为10000时，JMeter测试会出现错误，不会终止线程，也会挂起而不终止执行。

我在这里做错什么了吗？如何消除这些错误？
我在JMeter日志文件中没有看到任何异常行为。
如果你的问题是关于2984个失败的请求，那么它没有提供足够的失败原因信息。
- 检查.jtl结果文件，通常它包含HTTP响应状态代码和消息，这些代码和消息可能会揭示失败的原因
- 检查应用程序日志
-
您可以通过向user.properties文件添加下一行来临时配置JMeter以保存完整的响应数据：
jmeter.save.saveservice.output_format=xml jmeter.save.saveservice.response_data.on_error=true通过这种方式，您将在.jtl结果文件中获得完整的响应，这样您就可以确定应用程序过载时最终用户会得到什么错误。
