I'm seeing lots of these in a gateway's wrapper log, but I don't see any errors/dropped history in the store and forward status overview:

```

How can I see what these are referring to? (also, are there any plans to make this more obvious in the logging?)

Could it be that there is a problem with the connection to the DB, or the DB harddrive is full?

I did find that there was a database for dev still in there, failing to connect, but there are no tags that I know of that use the dev database for history... But that would make sense if there are. I deleted the database since its not needed, and the errors seemed to go away, but I'm going to wait and see. I'll look into finding tags using that database as well, as they arent needed either
