Jmeter | Uncaught Exception java.lang.OutOfMemoryError: unable to create new native thread.

Jmeter 在做性能测试的时候，控制台打印出下面的日志：

Don't use GUI mode for load testing, only for Test creation and Test debugging ! For load testing, use NON GUI Mode: jmeter -n -t [jmx file] -l [results file] -e -o [Path to output folder] & adapt Java Heap to your test requirements: Modify HEAP="-Xms512m -Xmx512m" in the JMeter batch file ================================================================================ Uncaught Exception java.lang.OutOfMemoryError: unable to create new native thread. See log file for details.

内存溢出, 下面方法来解决：

in the Jmeter 3.x. there are two steps to solve this problem.

Step 1, to modify the JVM memory in the JMeter batch file

## ============================================== ## Environment variables: ## JVM_ARGS - optional java args, e.g. -Dprop=val ## ## e.g. ## JVM_ARGS="-Xms512m -Xmx512m" jmeter etc. ## ## ==============================================

this is a default value in the jmeter.sh, according to your environment:

JVM_ARGS="-Xms512m -Xmx2048m"

in the jmeter.bat:

set JVM_ARGS=-Xms512m -Xmx2048m

Step 2, to Modify HEAP=”-Xms512m -Xmx512m” in the JMeter batch file:

in the jmeter.sh

HEAP="-Xms512m -Xmx2048m"

in the jmeter.bat:

set HEAP=-Xms512m -Xmx2048m
