I sat up last summer a mirrored instance of our main databases. In the last two month, we had twice issues on the main server and the roles never switched. I have little logs and no idea why it didn't switch.
You will find the general settings and server logs lower and lastly something strange I noticed at the same time so maybe linked.
Thanks for your time,
