Logging:System.Data.SqlClient.SqlException: Timeout expired. The
timeout period elapsed prior to completion of the operation or the
server is not responding.
i am a beginner when i saw in the application log files the above is the most frequent error i saw and also it is getting repeated everyday. on the database when i saw time taken for executing the particular procedure which the above function is calling is less than 5 secs.
But in the application we gave connection timeout=200s and by default command timeout=30 secs our manager says we don't have to increase the command timeout by anymore further as it is true. But still the exception is keep coming.
can anyone suggest me any solution so i can get rid of the above problem thanks
The setting in the web config, if it's the timeout in the connection string setting, is the connection timeout. It only applies to the time it takes to make a connection. From your problem description, it doesn't sound like a connection timeout is what's happening.
Command timeouts are specified in other ways. If you are using DataContext, for example, the timeout is set using the CommandTimeout property.

If you can give a code snippet of how you are hitting the database so we can see what classes you are using, more specific recommendations can be made.

I have a web app which has been added as a reference to my window service app. The service will call a method in the web app which then will invoke the database to run a stored procedure.
I received an exception while calling one of my store proc. The stored procedure will approximately run for 45 seconds. Below is the error
System.Data.SqlClient.SqlException (0x80131904): Execution Timeout
Expired. The timeout period elapsed prior to completion of the
operation or the server is not responding. --->
System.ComponentModel.Win32Exception (0x80004005): The wait operation
timed out
I have tried to increase the service app timeout by appending ';Connection Timeout=3600' to the service app conn string in web.config but the exception still occurred after around 30 seconds of running.
Your help to resolve this issue will be greatly appreciated.
To elaborate on #Squirrel comment:
Your error message shows a System.Data.SqlClient.SqlException. So the timeout is on SQL Server side.
So if you want to increase the timeout, it must be done on the SQL Server side.
In the System.Data.SqlClient namespace you seem to use, the SqlCommand class that you probably use to call your stored procedure has a property CommandTimeout that let you set the timeout value.
See the documentation
CommandTimeout
Gets or sets the wait time (in seconds) before
terminating the attempt to execute a command and generating an error.
My C# application is currently throwing lots of the below exceptions:
Timeout expired. The timeout period elapsed prior to completion of
the operation or the server is not responding. This failure occurred
while attempting to connect to the routing destination.
I am using linq queries and NHibernate.
I am having difficulty troubleshooting this as the exception does not occur every time the query is ran. If I take the query and run it directly on SSMS it seems to run very quickly.
The timeout exceptions only appear to occur when ran against one table in the database.
I know I am able to increase the query timeout but I would like to resolve the root cause of the issue. I have a limited knowledge in troubleshooting these issues so what are the next steps I need to take to determine what the problem is?
Increase 'Connect Timeout' of your connection string. 60 is a good number.
Timeout expired. The timeout period elapsed prior to completion of the
operation or the server is not responding.
I am getting this error in my project. Project is working fine for more than 2 years without this error. Now i am getting this error frequently.
What could be the reason for this? I have closed each and every opened connection. Is there any setting in SQL Server 2005 to avoid this issue? Or this problem is caused by network availability?
It could be due to network availability, but I had this problem some month ago.
In my case TCP/TP and share memory setting had changed in SQL Server Configuration Management.
Please check your SQL Server Configuration Management settings.
Today i have faced the same issue. So i collected all the logs.
In sql logs i got this error :
"Autogrow of file 'SSPB_log' in database 'SSPB' was cancelled by user or timed out after 30124 milliseconds. Use ALTER DATABASE to set a smaller FILEGROWTH value for this file or to explicitly set a new file size."
In my application logs I got this:
"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
Does this errors related to each other??
I've been getting this error recently, after several reloads of the same 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
So I am thinking there must be some queries or calls in the app I used incorrectly that causes them not to release the connection. Is there any tools out there that allows me to somehow peek into the pool to see who is hanging on to what?
There's a timeout property on your connection object that you can change. This will change the time it waits to get a connection, there's also a command timeout which controls how long it waits until the command times out once it is running (but the first one sounds like what you need) see here (anything that inherits from DBConnection should have this if you arn't using sql server).
Have a look here too, might help :)
In recent times, a particular page in my web app throws the
Exception Details: MySql.Data.MySqlClient.MySqlException: Timeout
expired. The timeout period elapsed prior to completion of the
operation or the server is not responding.
Though I use Ibtais as persistence layer, this error occurs. I have restarted the MySql service instance but stil i get the same error. It didn't happen earlier but happens frequently in recent times.
All the web applications deployed on the server uses Ibatis and the DB server remains on the same machine where IIS is installed. There are about 8000 records in which around 300 to 500 would be filtered on page load
Any insights for the cause of the problem?
I encountered the same problem with yours, and I found this MySQLConnection--Specifying default command timeout. Just add "default command timeout=xxx" into your connectString, this key's value is in seconds.
I tried and it worked for me.
You could set command timeout to 0, its not a good idea though. Some requests could go on indefinitely.
There is an underlying problem that is causing the queries to time out in the first place. Are you inserting, updating, or in any way working with large binary values that would lock the table? That is the most common reason I see for an error like this on such a small amount of data.
Make your connection string look like this:
DotNet Framework:
<add key="MYSQL_CONNECTION_STRING_RDS" value="Uid=userid;Password=pass;
Server=localhost;Port=3306;
Database=dbname;default command timeout=0;SslMode=none"
/>
DotNet Core
"MYSQL_CONNECTION_STRING_RDS": {
"ConnectionString": "Server=localhost;Database=dbname;user=userid;password=pass;default command timeout=0;",
"ServerVersion": "8.0.22"
}
