Jmeter-运行几个用户时出现java.lang.NullPointerException [英] Jmeter - java.lang.NullPointerException when running a few users

问题描述

我一直在进行jmeter压力测试，发现我无法解决的问题.

I've been working on jmeter stress tests, and found an issue that i'm not able to solve.

因此，如果我与一个用户一起运行一个测试计划，但都可以正常工作，那么我可以将其扩展到同时有25个用户.

So if I run a testplan with an user all works peachy, I'm able to scale it until 25 simultaneous users.

当我尝试使用26位用户进行任何升级时，都会收到以下错误消息.

As soon as I try to use 26 user using any ramp up I get the following error.
