I'm still getting intermittent, but frequent errors in the admin section of an Umbraco 3.0.5 installation when logging in and when clicking on content nodes:
Most recently, when logging in, the login box was missing the labels for the title and the username and password. Refreshing several times resulted in the labels eventually appearing, but when trying to login, I got the following error:
Server Error in '/' Application.

Has anyone experienced similar issues in 3.0.5, or suggestions to solve this?
Is the website in its own app pool in IIS?
I'll ask that question. It's on a server hosted by someone else so I don't have Remote Desktop connection to it. I've been told that nothing has changed on the server but it's being giving errors for several weeks but it's been on that server for a couple of years. It's the intermittent nature that makes it difficult to debug and I've been hoping that someone would have had this problem and recognised the errors. I'll let you know about the App Pool
I got to the bottom of this, finally.
I turns out there's a function call to an external service which appears on the home page. Removing this function call removed the problem. I don't have the source to the function so don't know what specifically within the function caused the problem. It only happened under load, so I had to run a load test tool on a test site while loading content nodes in the admin site, and remove elements from the home page until the problem stopped.
It also turned out that this problem only occurs on a server with asp.net framewrork 3.5 sp1 installed (my dev machine doesn't have since since it breaks older versions on AspDotNetStoreFront) so while testing, not only was there not enough load on the server to cause the problem, but the problem wouldn't have shown up anyway. I'll be upgrading the older dev server as soon as I can ditch the AspDotNetAstoreFront site.
Hopefully this might help anyone else with an intermittent problem with their site.
