Error occurred during initialization of VM Could not reserve enough space for 1048576KB object heap

Error occurred during initialization of VM Could not reserve enough space for 1048576KB object heap

errorlevel=1

首先根据报错信息去启动文件内搜索，查看是否是jmeter.bat内部配置，查找set HEAP参数

 我的是jmeter5.4版本默认是1g，shell命令是如果没有定义HEAP再设置HSEP的值

if not defined HEAP (
    rem See the unix startup file for the rationale of the following parameters,
    rem including some tuning recommendations
    set HEAP=-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m
)

其他JMETER是直接set  HEAP值那么根据需要增大该值
