Question

我大约在一天半之前突然在Eclipse IDE中出现GC错误和Java堆空间错误。这使我无法完成我的工作。 IDE只会停止响应几分钟，然后开始崩溃并出现GC错误。这些问题在IDE启动大约2分钟后开始发生。

这些错误只在打开文件或进行任何代码更改时发生，即使在运行任何代码时也是如此。 “从选择中请求JavaScript AST”出现错误

我尝试了几种解决方案。我有：

我创建了一个新工作区并导入了我的3个项目。
我最初使用的是STS。由于我目前的大多数工作都是使用nodejs，所以我下载了一个新版本的Nodeclipse。
我调整了eclipse.ini文件中的值。我已经调整了内存值和所需的java版本。我当前的ini文件如下所示：

-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417
-product
nodeclipse.package.enide.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms512m
-Xmx1024m

无论我做什么，问题仍然存在。有没有人对我有任何解决方案？这个问题似乎完全独立于我的eclipse安装和工作区。

以下是我过去一小时收到的错误列表：

Answer 1

某些eclipse插件效率很低，需要大量内存，尤其是在大型项目或解析合并源文件时。

所以1GB可能还不够。

如果将堆限制提高到几千兆字节并不能解决问题，那么其中一个组件可能只是内存泄漏。在这种情况下，您必须找出哪一个并为其提交错误。这可以通过进行堆转储并分析哪些类占用大部分内存来完成。
