xapool连接池不释放连接的问题。。。
公司一个项目跑了几个星期之后 就爆掉啦，查了一下日志如下：

网上有人说是oracle9i问题，Oracle9i有名的内存溢出bug导致:Xapool对PreparedStatement进行了Cache，同时Oracle 有一个出名的内存漏洞，PreparedStatement使用之后必须关闭，如果不关闭连续进行SQL查询会造成前面SQL的游标不能释放；

可是这个项目用的是oracle 10g

有没有人遇到过类似的问题 给点建议

------解决方案--------------------
我也碰到这个问题，用的oracle10g，正在寻找解决方案
