[解决办法]
内存溢出了。
1)检查程序有没有内存泄露。
2)把下面的Tomcat启动参数Xms和Xmx调大一点。
-Xms512m -Xmx512m
[解决办法]
Caused by: java.lang.OutOfMemoryError: Java heap space
内存溢出。

两种可能:
1、程序中存在内存泄露,这种情况下有多少内存都不够浪费的了;
2、确实程序需要较大内存,那么修改 Tomcat目录下 bin\catalina.bat,找到 “MEM_OPTS”,然后:

set MEM_OPTS= -Xms1024m -Xmx1024m 

注意前后留空格。
[解决办法]
内存溢出,断开重启服务器就行了。将jvm的内存设大些。
[解决办法]

探讨


这个我已经试了不行,我的程序就是一个扩展spring social框架实现微博三方登录,不会出现内存泄露吧


[解决办法]
1.可以在windows 更改系统环境变量
加上JAVA_OPTS=-Xms64m -Xmx512m

2,如果用的tomcat,在windows下,可以在
C:\tomcat5.5.9\bin\catalina.bat 中加上:
set JAVA_OPTS=-Xms64m -Xmx256m
位置在: rem Guess CATALINA_HOME if not defined 这行的下面加合适.

貌似这种的错误的发生是还没轮到具体项目的加载阶段,或者只是一种整体概念的加载,还未牵涉到项目内部具体的细节,和tomcat版本有关吗?能不能试着加载成功任意一个项目?
[解决办法]
OutOfMemoryError 明显是内存溢出
[解决办法]

添加的lib版本有问题啊?添加的lib版本有冲突?

[解决办法]
杀掉javaw进程,再运行就可以了。应该是虚内存引起的。
