In reply to ThomasLaRock. I have a witness. My networking team said there is nothing wrong with our network and the app and sql servers are right next to each other and plugged in into one switch. I have been getting this intermittent error very once in a while.

In reply to Louie Ortiz. Sounds like a network issues between the app and the database. If the app tries to connect to the principal, but can't, it could try to connect to the secondary. Are you using a witness server? Using a witness may help with this issue. For troubleshooting, I would look to monitor the network between the app and database servers, and I can recommend some great network tools for just that purpose.

I have mirrored configuration. Intermittently I get an error from the mirrored (secondary) server that the user cannot explicitly open database, this is because the mirror db has not failed over. My question is, why is the app cannot connect to the principal database? How can I find out what causing the connection error to the principal? Is there a way to find from principal if the connection has been refused? What is the best way to troubleshoot this issue?

In reply to Koen Verbeeck. I thought the same thing, so I bookmarked it and sorted my bookmarks so now it's not random.

I’m conflicted. Should I follow the advice of this random blog post? 🙂
