报错解决:http://www.cndba.cn/Marvinn/article/3277http://www.cndba.cn/Marvinn/article/3277http://www.cndba.cn/Marvinn/article/3277

修改server.xml文件中system标签值，

off heap for merge/order/group/limit 1开启 0关闭 —->修改配置文件值为： 0

添加如下： 0 http://www.cndba.cn/Marvinn/article/3277

       <system>
           ....中间配置省略....
         <property name="useOffHeapForMerge">0</property>
        </system>
