我有一个问题，我在我的电脑上使用 jmeter，它驱动安装在 RHEL5.8 上的 jmeter 服务器
我的 Java 版本是：
[jmeter@sem-osb logs]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.8 (Tikanga)
[jmeter@sem-osb logs]$ java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
我的电脑运行的是 ArchLinux。在两台电脑上我都使用相同版本的 Jmeter，即：jmeter.JMeter：版本 2.11 r1554548
因此，我尝试运行一个简单的测试，向 soap webservice 发出 3 个请求，并尝试模拟 2 个永远运行这些请求的客户端（我想加载服务器）。
一段时间后，我在 jmeter-server.log 上收到以下错误：

错误中提到的 IP 172.30.102.135 是我开始测试的 IP，也就是我的电脑。所以过了一段时间后，jmeter 服务器似乎无法再联系到我了。问题是我在此之前收到了很多结果，所以网络配置没有问题。测试停止是因为我要求它在出现任何错误后停止，但如果我不选中此选项，它就会继续，并在日志文件中添加更多错误。我在想也许可以在 /etc/security/limits.conf 中做些更改，但我不太确定。我真的很感激任何想法。
如果您需要更多详细信息，请询问。

我从这个网站获得了帮助：http://howtojboss.com/2012/07/31/concurrent-high-throughput-performance-testing-with-jmeter/
解决方案是使用这个参数，似乎当你打开太多连接时，用于旧连接的端口在 TIME_WAIT 状态下停留的时间太长，所以这有帮助：
echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle
