How can this be?  Isn't the purpose of Auto Create Statistics to avoid this situation?

Both Auto Create Statistics and Auto Update Statistics have been enabled for about a year, but the trace from the day before yesterday shows a number of Missing Column Statistics errors.

Can you post a couple of the actual errors?  Auto Create statistics only creates the stastistics for a column if that column is used in a Where clause, so its possible that you could have columns that have no statistics (because they've never been referenced in a where clause).  However, my understanding of the auto-create is that if its turned on, you shouldn't see these errors.
