我找到了一些解决这个错误的方法并相应地实施了。

实施上述链接中提供的解决方案后，我仍然收到此错误，Eclipse 仍然崩溃。
我正在使用 Eclipse Galileo、JDK 1.7、Apache tomcat 6.0。
在 eclipse.ini 文件中所做的更改
-Xms40m -Xmx512m -XX:MaxPermSize=512m
以前的值是
-Xms40m -Xmx128m -XX:MaxPermSize=128m
我已经进行了上述更改。但我仍然有同样的问题。
谁能帮我解决这个问题。

请仔细观察你的语法。如果您的问题由于语法错误而难以阅读，您将得不到答案。出于同样的原因，请避免使用聊天缩写。
-
您能否添加您所做的确切更改？
-
@soilworker 我已经提到了变化请检查它
-
到底是什么失败了？是 Eclipse 本身吗？您正在运行的程序？雄猫？
