（50分请教）一个很严重的数据库异常，高手请进！！

[yx580tnt]

我用odbc远程注册一个access数据库，可这种远程连接方式不太稳定，大概十多次会down一次虚拟机。

错误定位在这句上：Connection conn = DriverManager.getConnection("jdbc:odbc:db");
请问是什么问题引起的，如何解决？（只有我一人在操作，不能是多线程问题吧）
以下是报错信息：

jsp没有联接过access...

[kingdoom]

hs_err_pid4044.log 看看异常

[loulou82]

说一下具体的环境配置

是不是虚拟机模拟远程，和本地服务器共用一块网卡？

[wzrain]

驱动问题

[yx580tnt]

还有人知道是怎么回事吗，都说说自己的猜测吧。

[kampoo]

远程数据库肯定不行，access这种文件数据库尤其不行。以前在一个项目中用了oracle的远程数据库，经常掉线。最后只好换成了其他方式。
在access数据库所在主机部署一个web server，所有对数据库的访问通过http协议进行，这种方式很稳定，就是效率慢些。

回 kampoo() ： 谢谢献计。

[yx580tnt]

回kingdoom() ：我贴出的英文的那一大段就是hs_err_pid4044.log的内容。
回loulou82(南京以外不考虑~) ：不是在模拟，能肯定和环境没有关系。
回wzrain(晨雨) ：要换成哪种驱动程序？
谢谢

[yx580tnt]

大家没别的办法了吗？
