【问题描述】：
我正在使用 SoapUI Pro 5.1.2 对 camunda BPM 引擎的 REST API 运行负载测试，我得到了大约 10-30% 的故障，但有以下异常.

- 在我的测试用例中，我按顺序执行了一系列 REST 调用。
- 负载测试属性 - 线程：100，Startegy：Burst，Burst Delay：10s，Burst Duration：5s，限制 1000 总运行。
我尝试将 SoapUI 的“套接字超时”选项设置为 300000，即 300 秒，我发现这是我在论坛上找到的唯一选项，但我仍然遇到这些错误。此外，正如我所提到的，并非所有 1000 次运行都是失败的，只有 10-30 % 的运行随机失败，除了这个例外。
有时，负载测试会成功，将总运行次数限制在 500 以下，即便如此，我也会遇到其中一些错误，而且是偶尔出现的。
从上面的跟踪中，我知道问题出在客户端 (SoupUI) 方面（或者我的理解不对？）并且想知道如何解决这个问题？
