请问tomcat一段时间就死机是什么情况？

[小营123]

和数据库的链接有关系吗？

有错误日志没有？

[hebeiliuzhao0909]

内存泄露了

[编程小妞儿]

java.lang.OutOfMemoryError: PermGen space
内存溢出。。。

解决方法也一定是加大内存。
如果你的WEB APP下都用了大量的第三方jar, 其大小 超过了jvm默认的大小(4M)那么就会产生此错误信息了。

把你的jar包放在tomcat的lib里面，或者改jvm的内存

你好，我放过去启动时报错：

如何改jvm的内存？大哥。

谢谢了。

[niit_like]

写一个批处理，来启动tomcat

@echo off

set JAVA_HOME=D:\Program Files\Java\jdk1.6.0_20
set PATH=%JAVA_HOME%\bin
set CLASSPATH=.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar
set JAVA_OPTS=-Xms256m -Xmx512m -Duser.timezone=GMT+08 -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n -Dcom.sun.management.jmxremote

C:
CD C:\Program Files\apache-tomcat-6.0.20\bin
startup.bat

你好，我的tomcat是解压开就可以用的，bin目录下就有个startup.bat,我只要加入：
set JAVA_OPTS=-Xms256m -Xmx512m -Duser.timezone=GMT+08 -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n -Dcom.sun.management.jmxremote

就行了，对吧？大哥

[niit_like]

试试看吧

兄弟，这个如何解决啊?

[roemin]

修改 tomcat\bin\Catalina.bat 文件
在166行左右
rem Execute Java with the applicable properties ”以下每行
%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS% -Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" -Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" -Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION%

在 %DEBUG_OPTS% 后面添加-Xms256m -Xmx512m

保存后，重新以命令行的方式运行 tomcat ，即可，然后通过最后面介绍的如何观察tomcat现有内存情况的方法进行查看是否已经变更成功。

[小营123]

java.lang.OutOfMemoryError: PermGen space

PermGen 是存放加载的class的空间。 这个调Xmx Xms没用， 你需要适当的调一下这个参数：
-XX:PermSize=256MB -XX:MaxPermSize=256MB

[muyipan]

内存溢出了

[fh13760184]

系统常量较多 持久代 内存不足



将 -XX:MaxPermSize=n: 这参数调大 即可

[wxbhlj]

数据库连接的配置非常不好，虽然和OutOfMemoryError没关系。
