ADO.NET :: System.InvalidOperationException - Timeout Expired?
Sep 9, 2010
I am getting the following error on my page:
System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection
owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Open() at _default.commentCount(Int32 ArtID) at ASP.default_aspx.__DataBind__control4(Object

Hopefully I am posting this in the correct forum.
I am having a problem with my ASP.Net Web application. The application is developed using vb.net and is linked to a SQL Server database. Let me explain how the application works and the problem I am experiencing. The system is an online web app which allows registered users to create a CV online. One of the pages within the app gives users the chance to add a cover note to their CV. The page that allows them to do this consists of only a textarea control and a button control. The textarea allows users to input up to 4,000 characters.
Once the user clicks the 'Save' button to save their cover note info, the following code then executes.This code checks to see if the CV already has cover note info, if it does, then the application runs an update statement, otherwise, it runs an insert statement.The table within the database which records the cover note information is called tbl_covernote and has three columns, covernote_id (int and autoincrement), cv_id(int), covernote_text (nvarchar(max)).
The error which occurs sometimes is as follows:
Dim dr As SqlDataReader
Dim param(0) As SqlParameter

The problem is I have a stored procedure that runs consistently in Sql Server Management Server with a time of 2 seconds but when calling that same stored procedure from code it times out.
When it runs correctly from SSMS it should return about 30 rows.
I've tried a few different ways to call the procedure from code but every time the same result. This just recently started happening, yesterday it was working fine.
The preferred method for calling the procedure for us is using Linq2Sql which gives the following error message:

We are seeing the following timeout error being logged into our Event Viewer every now and then. We are using LINQ to connect to the SQL Server 2008 and the connection string is defined in the web.config file.One wierd thing I noticed is that the .NET framework is timing out trying to detect if this is SqlCe connection string. Why is it trying to waste time and then timing out when we have a SQL Server 2008 as the database?
What can I do to fix this problem?
Server: Windows 2008 R2 64-Bit
\IIS 7.5.7600.16385 Application Pool: Integrated Mode with 32-Bit Applications Enabled. Queue Length = 5000, Indentity = Network Service.Database Server: SQL Server 2008

I am using static class to do every job related to Database. In this class Connection Object is static but i am creating command object in the method. I read a form post here [URL] about creating connection object local. If we do like that how can we use Connection pooling? There is an example code below.
I am creating a connection object with pooling (Validate Connection=True; Min Pool Size=10; Max Pool Size=200; Incr Pool Size=10; Decr Pool Size=5;). I am expecting to use connection pool by static connection object (this obje has a connection poll) with dynamicly created commands. Am I wrong? Sometimes i am getting "System.InvalidOperationException: Operation is not valid due to the current state of the object." error. Is it because static connectin object?

We have been getting this Oracle connection pool exception a lot recently for our ASP.NET website. This is the detailed exception message:
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
This is our connection string
User ID=user1;password=password1;DATA SOURCE=Datasource1
how to set max pool size to 1 so that I can debug it on my local?
what is the recommended pool size for a website with 10,000 users?

I'm trying to set up a page that will allow users to download files from a shared drive (where the file is actually sent via the page). So far this is what I have.
public partial class TestPage : System.Web.UI.Page
{
protected DirectoryInfo dir;
protected FileInfo[] files;
protected void Page_Load(object sender, EventArgs e)
{
dir = new DirectoryInfo(Server.MapPath(@"\sharedDrivePublic"));
files = dir.GetFiles();
}
}
The aspx page looks kind of like this:
<% Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name); %>
<ul>
<% foreach (System.IO.FileInfo f in files)
{
Response.Write("<li>" + f.FullName + "</li>");
} %>
</ul>
When I remove the erroneous parts of the code, the page tells me that the Windows Identity I'm using is my user (which has access to the drive). I don't understand what the problem could be or what it's even complaining about.

VS2010/C#. I have a gridview bound to a SQL Server table with the default SELECT statement returning only a few rows. This is straight out of the box, so no need to show markup.
Upon a button click event I update the datasource: SqlDataSource1.SelectCommand = hdnSQL.Value; Then bind: qlDataSource1.DataBind();
But when I run this, I get this error:
System.Data.SqlClient.SqlException was unhandled by user code. Message=Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I am clueless. I have done this many times in the past and NEVER encountered a timeout.

We have the timeout value set to 120 in our <form> tag within the web.config. We do not have a session timeout set.. and we have various connection strings.
We are having a problem where a session variable will disappear (become NULL) .. but, the form evidently remains 'open'.. or no re-login is required..... so, my question(s):
1. what is the relationship between form timeout and session timeout
2. how do I set session timeout

I have an ASP.Net application that makes an AJAX request to retrieve at report. The report can run for a long time so I set the asyncpostbacktimeout in <asp:ScriptManager /> to 600. However, when I try to run the report, if it runs for longer than 90 seconds it fails to come back. I can see in the IIS logs that the POST request succeeded with a 200 status and I can see the time taken is much less than 600.
The web page dutifully waits for the entire 600 seconds before returning with a timeout error:
Error:
Sys.WebForms.PageRequestManagerTimeoutException:
The server request timed out.
Is there any setting I should be checking in IIS? Connection timeout is 900 seconds.
