Question

我正在使用以下命令下载大小为450MB的视频：

JVM_ARGS="-Xms1024m -Xmx4096m -XX:NewSize=512m -XX:MaxNewSize=512m
-XX:+UseConcMarkSweepGC"  && export JVM_ARGS && ./jmeter.sh -n -t  .../jmx_Tests.jmx -l jtlfilename.jtl

jmeter.bat文件配置为：set HEAP=-Xms1g -Xmx4g -XX:MaxMetaspaceSize=512m

java.lang.OutOfMemoryError: Java heap space

但是下载16个文件后出现内存不足异常。然后我更改为-Xmx5120m，但仍然抛出相同的异常。
