我使用的数据源



<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

		<property name="driverClass" value="com.mysql.jdbc.Driver"/>  

    	<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/jike"/>  

    	<property name="user" value="root"/>  

  	    <property name="password" value="root"/>  

  	     <!-- Connection Pooling Info -->

  	     <property name="initialPoolSize" value="5"></property>  

   	 	 <property name="maxIdleTime" value="100"></property>  

   		 <property name="maxPoolSize" value="50"></property>  

     	 <property name="minPoolSize" value="5"></property> 

	</bean>

eh缓存的配置



<bean id="cacheManager" class="net.sf.ehcache.CacheManager">

	</bean>

	<cache name="sessionCache"  

    	maxElementsInMemory="1000"  

    	eternal="false"  

    	overflowToDisk="true"

    	diskExpiryThreadIntervalSeconds="120"  

    	memoryStoreEvictionPolicy="FIFO"

tomcat第一次启东市正常启动，但是reload项目是就有最上面的严重错误，reload一次到不碍事，多了就会内存溢出，异常我就不贴了。Tomcat:Caused by: java.lang.OutOfMemoryError: PermGen space；很明显内存泄露，但是我不知道如何解决，求大神分析一下啊
