You would need to determine what queries are being run. This will be in the code or you can use Profiler to check what is happening.

From there, try running that code in SSMS and see if it works.

Any other chances for getting the time out error to happen

I'd suspect pretty strongly you're getting blocking. If you have a blocking script, I'd run it (if not search for one in the SSC scripts over on the left), or at least run sp_who2 to see what's being blocked. Also get perfmon spun up & start collecting data on CPU, memory, etc., to see what the system is doing. As Steve says, get a server-side trace set up so you can capture data.

That's what I'd do now. If you get information from these, pass it on.

Try doing these

First:

In database property set query time out to 0, It's default vaule is 600.

Second:

In your connection string add "Connection Timeout = 0"

Third:

When you executing your stored procedure or query, that time you also need to set SqlCommand's CommandTimeout to 0.

Ex. : cmdExecute.CommandTimeout = 0;

Tanx 😀

Editor's Note: I'm not sure what this means, but I suspect it is a non-English, non-appropriate language, so I have removed it.

You're most probably on the money. Add connection pooling to this !

I use connection string settings from web.config where I add parameters for connection timeout and set a maximum connection pool of ... say 30 connections or whatever stabilises your SQL Server.

If you use Activity Monitor, you'll be amazed at the number of pooled connections generated by each .Net call. Not only they may block one another, but they certainly exhaust the server resources.

Sorry I cannot give an example, not close to a work computer, but there is good documentation around that I used successfully.

I do not think there is anything like that.

In general at server side there is no timeout thing.
