java.lang.OutOfMemoryError: PermGen space

6个回答

第一种,在你安装的tomcat目录下找到bin/catalina.sh,在“echo "Using CATALINA_BASE: $CATALINA_BASE"”上面加入以下行: JAVA_OPTS="-server -Xms800m -Xmx800m -XX:MaxNewSize=256m"
第二种,在你运行的Eclipse项目下的Servers右键-->Debug As-->Debug Configurations-->
图片说明
的最后加上-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxNewSize=256m -XX:MaxPermSize=256m
-Dfile.encoding=UTF-8

持久代内存溢出了,检查一下是不是重复加载了jar包,或者是不必要的包就不要加载了;
还是就是调高启动时的maxPermSize参数;

希望可以帮到你....

内存溢出, 你可以 把配置调大 一些。

内存爆掉了,解决办法按楼上说的做

java.lang.OutOfMemoryError: PermGen space 内存溢出 tomcat运行内存调大点

内存溢出。参加链接可解决:http://blog.csdn.net/fengyie007/article/details/1780375/

关于hibernate的问题,一个项目刚导入时可以运行,但在果断时间后再次运行就报500错误

具体情况介绍,在某网站下载了一份开源代码之后,第一次导入Eclipse,是可以运行的。但在一段时间之后,再次运行报500错误。期间没有对代码有过任何修改。删除该项目重新解压一份并导入后又可以运行,但过段时间后又不能运行。感觉这个问题很奇怪,有没有大神懂。 下面我说一下今天的情况:下午又导入了一次,运行时没问题的,然后我停掉tomcat后,紧接着又运行了一遍,还是可以的。之后我就不再运行这个项目。看了另一个,做测试的作业。结果晚上回来后想要再次验证下该项目,重新运行,又报500错误。 疑惑: 1.假如说是hibernate或其他相关包导入错误的问题,那么,为什么重新导入后第一次可以运行 2.加入不是hibernate或其他相关包导入错误的问题,那为什么报500错误跟其有关 3.感觉这个问题很是奇葩,难道是内存回收机制方面的问题 …… 很奇怪的一个现象,希望能有大神解答。PS:我会在下面贴报错信息。
