We use SqlDependency to cache some lookup tables to our IIS servers, and have database mirroring configured as well. Just recently when I went to do an online rebuild of a few indexes to change the fillfactor (as there was wasted space in these particular
ones) I found that the service broker queries monitoring the lookup tables all started failing - not for the duration of the index rebuild, but for the duration of the mirror catching up with all of the transactions. Is this expected behavior for
SqlDependency and database mirroring?
