eclipse 出现内存不足的错误，为什么？

发布于 2024-11-25 18:44:39 字数 77 浏览 1 评论 0原文

当我在“Eclipse”IDE 中创建一个新项目时。突然它显示一条警报消息“内存不足错误”。我无法确定原因。 如果有人知道原因请告诉我。

If any one know the reason please tell me.

尝试使用以下参数启动 Eclipse：

eclipse.exe -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m

或者根据您的要求调整这些参数

Try to start eclipse with follow paramenters:

eclipse.exe -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m

Or justify these parameters for your requirements

  1. 转到 Eclipse 安装文件夹

  2. 如果您在 Mac OS X 上运行 Eclipse

    右键单击eclipse.app图标

    单击显示包内容

  3. 打开eclipse.ini文件

  4. 更改以下参数

    <前><代码>-Xms512m
    -Xmx3000m（希望您的开发者盒子有 >4GB 内存）

  5. 添加以下参数

    <前><代码>-XX:PermSize=256m
    -XX:MaxPermSize=512m

  1. Go to your Eclipse setup folder

  2. If you are running Eclipse on Mac OS X then

    Right click on eclipse.app icon

    Click on Show Package Contents

  3. Open eclipse.ini file

  4. Change below parameters

    -Xms512m
-Xmx3000m (Hoping your developer box has >4GB of memory)

  5. Add below parameters

    -XX:PermSize=256m
-XX:MaxPermSize=512m

最明显的解释是你确实失忆了。在这种情况下，使用更大的堆启动 Eclipse 应该有助于

 -vmargs -Xmx256M

改变 256M，看看什么适合您。

如果您只有几个简单的项目，我不会期望看到这个问题。如果您正在使用其他插件，那么可以想象您需要的堆数量可能需要增加。

The most obvious explanation is that you are truly out of memory. In which case starting Eclipse with a bigger heap should help

 -vmargs -Xmx256M

varying the 256M to see what works for you.

I would not expect to see this problem if you have just a few simple projects. If you are using additional plugins then conceivably the amount of heap you need may need to be increased.

不确定是否与您的问题相关，但我刚刚在使用 OpenJDK 7 的 Swing 项目中遇到了类似的问题。

经过几次启动（Run 按钮）和关闭（'X'< /code> / Alt+F4) 我的应用程序，我在控制台中收到此错误：

Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread
    at java.lang.Thread.start0(Native Method)

    at java.awt.Window.setVisible(Window.java:1014)
    at tool.BAT.main(BAT.java:11)

有时，我收到另一种错误：

Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread

然后，如果我尝试再次运行它，Java 崩溃了:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x0000000000000000, pid=30388, tid=139776854689536

top 揭示了问题的原因（注意虚拟内存使用情况）：

PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
30619 mcmlxxxv  20   0 3271m 390m  45m S   2.0 13.0   0:38.88 java
30667 mcmlxxxv  20   0 2172m  35m  12m S   0.3  1.2   0:01.00 java
30688 mcmlxxxv  20   0 2172m  35m  12m S   0.3  1.2   0:00.96 java
30710 mcmlxxxv  20   0 2172m  35m  12m S   0.0  1.2   0:00.97 java

这些都是我的应用程序的实例，尚未关闭。仍然不确定为什么每个实例分配这么多虚拟内存 - 可能有一些选择。 （顺便说一句，我有 3GiB 的物理内存）。

这是我的 main() 方法：

public static void main(String[] args) {
    JFrame frame = new JFrame();
    //frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 300);
    frame.setVisible(true);
}

我在教程中看到了注释行，并专门将其禁用以查看会发生什么。发生的情况是它默认为 HIDE_ON_CLOSE，它不会关闭和处置框架。

将 setDefaultCloseOperation 设置为 EXIT_ON_CLOSE 是我的解决方案。不过，有兴趣看到更多知识渊博的人对此的意见。

Not sure if relevant to your problem, but I just had a similar problem with a Swing project using OpenJDK 7.

After several cycles of starting (the Run button) and closing ('X' / Alt+F4) my application, I got this error in the console:

Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread
    at java.lang.Thread.start0(Native Method)
    at java.lang.Thread.start(Thread.java:691)
    at sun.awt.AWTAutoShutdown.activateBlockerThread(AWTAutoShutdown.java:334)
    at sun.awt.AWTAutoShutdown.notifyPeerMapUpdated(AWTAutoShutdown.java:215)
    at sun.awt.AWTAutoShutdown.registerPeer(AWTAutoShutdown.java:348)
    at sun.awt.SunToolkit.targetCreatedPeer(SunToolkit.java:313)
    at sun.awt.X11.XToolkit.createFrame(XToolkit.java:410)
    at java.awt.Frame.addNotify(Frame.java:477)
    at java.awt.Window.show(Window.java:1031)
    at java.awt.Component.show(Component.java:1651)
    at java.awt.Component.setVisible(Component.java:1603)
    at java.awt.Window.setVisible(Window.java:1014)
    at tool.BAT.main(BAT.java:11)

And sometimes, I got another sort of error:

Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread

and then, if I tried to run it once more, Java crashed:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x0000000000000000, pid=30388, tid=139776854689536

top revealed the cause of the problem (notice virtual memory usage):

PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
30619 mcmlxxxv  20   0 3271m 390m  45m S   2.0 13.0   0:38.88 java
30667 mcmlxxxv  20   0 2172m  35m  12m S   0.3  1.2   0:01.00 java
30688 mcmlxxxv  20   0 2172m  35m  12m S   0.3  1.2   0:00.96 java
30710 mcmlxxxv  20   0 2172m  35m  12m S   0.0  1.2   0:00.97 java

These were all instances of my application, which had not been closed. Still not sure why so much virtual memory was allocated per instance - probably there's some option for that. (I have 3GiB of physical memory, by the way).

Here's my main() method:

public static void main(String[] args) {
    JFrame frame = new JFrame();
    //frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 300);
    frame.setVisible(true);
}

I saw the commented line in a tutorial and specifically disabled it to see what would happen. What happened was that that it defaulted to HIDE_ON_CLOSE, which did not close and dispose of the frame.

Setting setDefaultCloseOperation to EXIT_ON_CLOSE was the solution for me. Interested to see input from more knowledgeable people on this, though.

  • 打开您的 eclipse.ini 文件
  • XXMaxPermSize 将为 256m。
  • 将值更改为 512m。
  • 重新启动你的日食。
  • 现在您将不会在 Eclipse 中看到任何内存问题。

简要说明如下：

之前

--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m

之后：

--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
  • Open Your eclipse.ini file
  • XXMaxPermSize will be 256m.
  • Change the value to 512m.
  • Restart your eclipse.
  • Now you will not see any memory issues in Eclipse.

In Brief See below:

Before

--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m

After:

--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m

对于每个在没有修复它的情况下最终陷入底部的人（像我一样）...

每次我尝试保存特定文件时，我的 Eclipse 都会耗尽内存。

Eclipse 有一个错误，它无法处理方法类型和方法名称之间的注释格式，如下面给出的代码。解决方法是将评论向上或向下移动

public String 
  // Never put a comment here, Eclipse will run out of memory
  getName() {
   return "name";
  }

For everyone (like me) who ends up at the bottom without fixing it...

My Eclipse ran out of memeory every time I tried to save a specific file.

Eclipse has a bug where it is unable to handle formatting a comment between a method type and a method name, like the code given below. The fix is to move the comment up or down

public String 
  // Never put a comment here, Eclipse will run out of memory
  getName() {
   return "name";
  }

您必须使用 setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

您可以从这里看到

You have to use setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

You can see from here
