Execution Timeout Expired on rebuilding Cache

system · May 5, 2019, 6:43pm

For a website I’m building I was creating a test. I’ve made a loop that would make 8000 nodes in the tree. So far so good.

After a bout 1500 I stopped the process, to do a few other things first. But when visiting my site I kept getting:

Welcome to your Umbraco installation
You’re seeing this wonderful page because your website doesn’t contain any published content yet.

When checking “Published Status” all seemed ok. I can Rebuild the Database Cache, but when pressing “Reload” I get an timeout. I’ve tried stopping/starting services and the server. But I can’t get my site up and running again.. (It’s a test database lucky).

I’m now afraid this will happen on my live site aswell when reaching a higher amount of nodes.. Any tips?

System.Data.SqlClient.SqlException: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
