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？我试过改变JVM一百次。与eclipse.ini混淆似乎没什么用。

我在RHEL5 AMD64上运行Eclipse 64 3.7.1;

Exception in thread "Worker-4"

我试过在eclipse.ini文件中增加内存。以下是崩溃时的一些错误：

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

openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=256m
-Xms1024m
-Xmx1800m

我在这里再次提出这个问题：Setting JVM maxperm size outside of Eclipse.ini并且对于遇到此问题的其他人都收到了一个很好的答案。

Answer 1

使用java.lang.OutOfMemoryError可能导致日食崩溃的潜在问题很多。

检查您的机器是否内存不足。您可以使用free命令执行此操作。但是，内存不足很可能不会以这种方式显示，除非您已禁用overcommit。

使用ulimit -v命令检查每个进程的虚拟内存大小限制。

允许JVM使用-Xmx标志获取更大的堆。

您的日食可能会加载很多插件。每个插件都包含许多类，所有这些类都存储在堆的永久生成中。尝试使用-XX:MaxPermSize JVM标志禁用某些插件或增加永久生成大小。

编辑：既然已经使用完整堆栈跟踪和异常消息字符串扩展了问题，很明显永久生成大小不足。因此，如上所述，使用-XX:MaxPermSize增加其大小或尝试禁用某些插件。也许你最近添加了一个包含很多类的插件？

Answer 2

也许说明显但是内存不足，你的电脑内存不足吗？

尝试使用vm args运行它以分配更多内存。

eclipse -vmargs -Xmx512m

Answer 3

仅限此日志。据我所知，这是与内存大小相关的问题。你有没有尝试过看看Eclipse启动时的内存量？您是否配置了任何默认的JVM参数。在Eclipse启动后，您可以从终端使用'ps -aux'检查正在运行的Eclipse进程。

您应该看到类似-Xmx512m或-XX：MaxPermSize = 128m的内容。您可能还想查看一下eclipse.ini，看看是否存在一些与内存相关的设置。

Eclipse崩溃了
