Hello,
I just notice that the newsfeed on “My Site” was empty after the SharePoint WFE restarted. After I examined event viewer log, I found out that the account used for user profile’s application pool cannot access the content database other that “My Site” content database. Soon after I added SPDataAccess *which I never revoked* to the entire content database, “My Site” began showing the newsfeed from others site again even though not all of them.
So, I there any precaution I need to take when I want to restart the WFE Server or the DB Server? Is the Account for User Profile Application Pool supposed to have SPDataAccess for all others content database or not?
