Jmeter缓冲区空间

Question

我使用J-meter在Web服务上运行一些负载场景。

我送与75个并发用户的请求三十分钟但大约五分钟后，我得到这个错误：如果您在Windows Server 2008 R2或Windows上运行的JMeter

Answer 1

7，你应该申请KB2577795 HotFix

如果你在Linux上运行JMeter的，下面一行添加到/etc/security/limits.conf：

foo soft nofile 4096 
foo hard nofile 65536 

凡foo应该是你的Linux用户名

此外，通过运行下一个命令设置一个硬性限制：

ulimit -n 8192 

还检查了以下参考：

Answer 2

除了这种潜在的重复：

• java.net.SocketException: No buffer space available (maximum connections reached?): JVM_Bind

Uou不应使用SoapSampler了。

阅读此为最新的方法来测试皂WS：

此外，确保您使用JMeter的最后版本。
