java网站，关于jdbc连接池的问题报错，紧急，请大神指点！！！解决不了又要被老板骂了。
[align=center]项目启动后按F5一直刷新网站主页，
1.刚开始刷新后异常的信息为：java.sql.SQLException: We are already in the process of making 11 connections and the number of simultaneous builds has been throttled to 10
2.刷新一段时候后异常的信息为：java.sql.SQLException: Couldn't get connection because we are at maximum connection count (200/200) and there are none
3.最后报内存溢出异常。[/align]
代码我检查了没问题，pst,rs,conn该关闭的都关闭了，访问主页的19个查询方法也是平级的概念。

[解决办法]
楼主用的是oracle吗？
是不是驱动版本的问题啊
[解决办法]
<simultaneousBuildThrottle>69</simultaneousBuildThrottle>
<minimum-connection-count>20</minimum-connection-count>
<maximum-connection-count>200</maximum-connection-count>
这个设置的不合理，改为
<simultaneousBuildThrottle>20</simultaneousBuildThrottle>
<minimum-connection-count>5</minimum-connection-count>
<maximum-connection-count>50</maximum-connection-count>
[解决办法]
看看你写的数据库连接 释放自动释放
