linux - Eclipse 崩溃

Question

我在运行 eclipse 时遇到了问题。这是今天崩溃后​​抛出的异常。我不明白为什么我不能在我的 Linux 机器上运行标准的 eclipse。有谁知道问题可能是什么？我试过一百次更改 JVM。弄乱了 eclipse.ini 似乎没有任何效果。

我在 RHEL5 AMD64 上运行 Eclipse 64 3.7.1；

Exception in thread "Worker-4"

我试过增加 eclipse.ini 文件的内存。以下是崩溃时的更多错误:

这是我的 Eclipse.ini 文件:

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=256m
-Xms1024m
-Xmx1800m

我在这里再次问了这个问题:Setting JVM maxperm size outside of Eclipse.ini 并为遇到此问题的其他人提供了很好的答案。

Answer 1

可能有许多潜在的问题导致您的 eclipse 因 java.lang.OutOfMemoryError 崩溃。

检查您的机器是否内存不足。您可以使用 free 执行此操作命令。不过，内存不足很可能不会以这种方式出现，除非您禁用了 overcommit。 .

使用 ulimit -v 检查每个进程的虚拟内存大小限制命令。

允许 JVM 使用 -Xmx 标志获取更大的堆。

您的 eclipse 可能加载了很多插件。每个插件都包含一些类，所有这些类都存储在堆的永久代中。尝试使用 -XX:MaxPermSize JVM 标志禁用某些插件或增加永久代大小。

编辑:现在问题已经扩展到完整的堆栈跟踪和异常消息字符串，很明显永久代的大小是不够的。因此，如上所述，使用 -XX:MaxPermSize 增加其大小或尝试禁用某些插件。也许您最近添加了一个包含很多类的插件？
