Answer 1

You have an ajax request that's taking too long to complete. It would help if you can isolate the request and share what it's trying to do.

Answer 2

It is an Ajax error - do you only get the error when debugging? If you want to increase this timeout then set the AsyncPostBackTimeout of your script manager to something large

Answer 3

This happens if you sit there too long trying to step through your ajax request. Either increase the timeout or work faster.

Incidentally, I believe the timeout setting defaults to 90 seconds. See this for more information.

Answer 4

I don't see anything immediately obvious in that error message to suggest it's a SQL server request that's timing out rather than any other sort of "server request". However, if it is, stick a profiler on your SQL server to see which request is taking a long time - and find out whether it's just a query which needs speeding up, a deadlock, or something like that.

Another possibility is that it's the connection pool - if you're not closing your connections properly, you could be timing out waiting for them to be returned to the pool. If that's the case, you obviously won't see the request in the SQL profiler.
