服务器的outofmemory问题的解决

现在我的服务器抛了如下的异常：

Exception in thread "ContainerBackgroundProcessor[StandardEngine[Catalina]]" java.lang.OutOfMemoryError: Java heap space
Oct 22, 2007 7:53:54 PM org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run
SEVERE: Caught exception (java.lang.OutOfMemoryError: Java heap space) executing

org.apache.tomcat.util.net.LeaderFollowerWorkerThread@369ac7, terminating thread
Exception in thread "DefaultQuartzScheduler_Worker-9" java.lang.OutOfMemoryError: Java heap space

当时曾经出现过类似的异常，但报错内容不一样，好像是java.lang.OutOfMemoryError: PermGen space异常。看错误情况异常的位置不一样了。对于permgen的异常，当时看到论坛里面这篇文章可以解决：

对于我现在面临的问题，我还没有遇到过，还不知道该如何解决呢～

这里已经有比较完善的讨论了，呵呵

还有这里：
If Java runs out of memory, the following error occurs:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
This can have two reasons:

Your Java application has a memory leak. There are tools like YourKit Java Profiler that help you to identify such leaks.
Your Java application really needs a lot of memory (more than 128 MB by default!). In this case the Java heap size can be increased using the following runtime parameters:
java -Xms<initial heap size> -Xmx<maximum heap size>
Defaults are:

java -Xms32m -Xmx128m
You can set this either in the Java Control Panel or on the command line, depending on the environment you run your application.
