网站本地调试都不会出现这个问题！传到服务器上之后浏览一会就会出现这样的问题！然后刷新一下又可以，再浏览一会又出现！
百度了下发现不少人也出现过这样的问题，但答案都千篇一律，没有效果！
堆栈跟踪:
- C# code
[OleDbException (0x80004005): 未指定的错误] System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection) +968349 System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) +86 System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup) +29 System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) +4862012 System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) +117 System.Data.OleDb.OleDbConnection.Open() +40 DAL.sqlHelper.ExecuteReader(String cn, String cmdText) +200 DAL.QTshowServer.NowLocation(Int32 loca, Int32 tcid) +361 BLL.QTshow.NowLocation(Int32 loca, Int32 tcid) +51 products.Page_Load(Object sender, EventArgs e) +947 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +99 System.Web.UI.Control.LoadRecursive() +50 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627
上面的堆栈跟踪看不太懂，不知道是哪里错误了，不过我想应该在数据库方面，浏览页面也就是查询数据库的时候，请问有什么好的解决方法吗？

及时释放资源，关闭连接，数据库操作类
并发访问
操作权限
