We have two web servers and two database servers with a load balancer directly traffic as you would expect.
The web farm mode is set to manual and we have entered the keys into the web configs for Server001 and Server002 with everything ticked for allow synchronization for.
The site runs fine initially orders go through, task are processed on the bus, web server tasks are processed as expected. But the more traffic that comes through the site the worse things become until the site eventually crashes and I have to restart both servers.
We get time out errors of: [DataConnection.HandleError]: Query: SELECT * FROM CMS_WebFarmServer Caused exception: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
