jmeter测试因内存不足错误而失败 [英] jmeter test failed with out of memory error

问题描述

当尝试使用50或更多用户运行jMeter时，它会显示OutOfMemoryError：

When try to run jMeter with 50 or more user it gives OutOfMemoryError:

2013/12/18 13:35:15 ERROR - jmeter.threads.JMeterThread: Error processing Assertion  java.lang.OutOfMemoryError: Java heap space
2013/12/18 13:35:15 ERROR - jmeter.threads.JMeterThread: Error processing Assertion     java.lang.OutOfMemoryError: Java heap space
2013/12/18 13:35:15 ERROR - jmeter.threads.JMeterThread: Error processing Assertion  java.lang.OutOfMemoryError: Java heap space
2013/12/18 13:35:15 ERROR - jmeter.threads.JMeterThread: Error processing Assertion  java.lang.OutOfMemoryError: Java heap space
2013/12/18 13:35:16 ERROR - jmeter.threads.JMeterThread: Test failed! java.lang.OutOfMemoryError: Java heap space
2013/12/18 13:35:17 ERROR - jmeter.threads.JMeterThread: Test failed! 

我试图增加堆大小但仍然得到相同的错误。

即使我试图删除所有的听众，但没有任何改变。

I tried to increase the heap size but still getting the same error.
Even i tried to remove all the listeners but nothing changed.

推荐答案

看起来你只是缺少Java堆空间。这是正常的，因为默认情况下JMeter的堆分配非常低。它可以通过 -Xmx 参数控制。

It looks like that you're just lacking Java Heap Space. It's normal as JMeter by default has a very low heap allocation. It's controllable via -Xmx parameter.

jmeter.bat 或 jmeter.sh 建议启动JMeter的脚本

There is a line in jmeter.bat or jmeter.sh script which recommends launching JMeter as

JVM_ARGS="-Xms512m -Xmx512m" jmeter.sh

您可以尝试增加最大堆，直到您停止接收这些错误为止。我建议将其设置为80％的硬件RAM。

You can try increasing maximum heap until you'll stop receiving these errors. I'd recommend to set it to something like 80% of your hardware RAM.

另请考虑 JMeter性能和调优技巧文章确保禁用内存消耗的侦听器，不要覆盖，有效地使用后处理器等。

Also consider JMeter Performance and Tuning Tips article to make sure that you disable memory-consuming listeners, don't overscript, use post-processors efficiently, etc.
