hibernate3使用了一段时间以后,Connection reset 无法连接数据库
APP:ORACLE 10G application Server
DB:ORACLE 10G
表示层使用STRUTS,持久化层直接使用hibernate3,没有用spring进行管理
连接使用APP server的DATASOURCE 进行连接
每次调用数据连接时,都会用HibernateSessionFactory.getCurrentSession()去取
使用后都会用,HibernateSessionFactory.closeSession()去释放连接

=========================================================================
使用了一段时间以后,页面会报错,但刷新一下又会恢复正常
再使用一段时间以后,数据连接就会断掉,刷新也无法恢复正常
只有重起APP的服务才能恢复正常
后台LOG信息报错如下
