    what if there are some particularly big tables which take hours and hours to run during the weekly maintenance (checkdb, then reindex above a certain fragmentation level, then update stats where last update > 24 hours ago) job, and are still running and causing user issues at the start of the business day? auto create and update are on btw.

    every article i can see is only concerned when apps run slowly due to outdated statistics.

    this is in a production environment and i can’t really suggest things (switching auto off, changing from fullscan to a percentage etc) when the result isn’t very predictable
