macos - OSX 上的 IntelliJ Idea 2016 内存问题

Question

我刚刚更新到 Idea 2016.3.2。并不断收到此错误。

There is not enough memory to perform the requested operation. Please increase 'Xmx' setting and restart the IDE for change to take effect.

我做的最后一件事是在 idea.vmoptions 文件中将 Xmx 内存选项增加到 2048(按照这个答案 How to increase IDE memory limit in IntelliJ IDEA on Mac? 的指示)

但它仍然不断耗尽内存。

有谁知道我需要做什么？

...在进一步研究之后，现在在我看来它是一个导致内存故障的 git 进程。当我打开一个 git 管理的项目时启动。

找到了解决办法:
将此添加到自定义属性(通过帮助菜单；编辑自定义属性)

vcs.log.index.git=off

这样 Idea 就不会尝试索引你的整个 repo 和
