Hi,
One of our sites recently had an outage I was hoping the community might have some ideas in diagnosing this.
I'm running:
Web Server: Windows Server 2003 R2 Standard Edition SP2, various DNN versions (the effected site was running 4.8.0).
DB: Windows Server 2003 R2 Standard Edition SP2, SQL Server Developer Edition ver 8.00.2039
I have about 20 DNN sites running on the webserver today one of them failed. When you visit the page it would be just blank like it was loading something. The other sites continued to work normally.
I tried a few site restarts and IIS restarts, but no dice. Finally it came back by itself. This is the first time something like this has happened.
I checked the logs for the site in question, a lot of this:

I don't believe it was a webserver issue since it was isolated to one site. From these log entries, can we say it's a db issue? Any suggestions on my next steps for troubleshooting this?
