Java的堆出太空错误 [英] Java Out Of Heap Space Error

问题描述

我通过一个Ant脚本运行的一个非常漫长的过程，我让下面的堆，但它仍然给我的错误。

 设置ANT_OPTS = -Xms1024m -Xmx2024M -XX：MaxPermSize参数= 512M
 

解决方案

我觉得奇怪，我说，你正在使用更多的2G执行版本（虽然它是完全可能的），所以我会做一些愚蠢的问题，只是帮你思考你的问题：

• 你真的确认ANT_OPTS设置是否正确？


• 您是否启动命令行或从IDE脚本？


• 您使用的是哪种操作系统？


• 多少物理内存已经在您的盒子有什么？


• 您使用的构建触发任何插件或工具？


• 您在构建期间发射试验？你在测试过程中分叉？

I'm running a very long process via an Ant script, I allowed the following heap but it still give me the error.

set ANT_OPTS=-Xms1024M -Xmx2024M -XX:MaxPermSize=512M

解决方案

It seems strange to me that you are using more 2G to perform a build (although it's clearly possible) so I'll make some silly questions just to help you thinking on your problem:

• Are you really sure that the ANT_OPTS is correctly set?
• Are you launching the script from command line or from an IDE?
• Which OS are you using?
• How much physical memory have you got in your box?
• Are you using any plugin or tool triggered by the build?
• Are you launching test during the build? Are you forking during tests?
