I thought it's enough. But the dialog shows from time to time, and sometimes, it's no responding that I have to shutdown it.
我以为这就够了。但是对话框不时显示，有时，我必须关闭它没有响应。

If you still see this popup frequently even with high memory allocated, try:
如果即使分配了大量内存，您仍然经常看到此弹出窗口，请尝试：
File > Invalidate Caches / Restart...
文件 > 使缓存无效/重新启动...

It really depends on the nature of the error. One thing to try is using idea64.exe instead of idea.exe.
这实际上取决于错误的性质。要尝试的一件事是使用idea64.exe 而不是idea.exe。
If this doesn't help, please contact JetBrains by filing an issue to https://youtrack.jetbrains.com/newissueand attach your log there (Help | Show log).
