What to do about this?
Then have a good look in your log-fil to see what was wrong. If there is a error. Save your current file. Make a repair of that file
Run a recover on a backup, inspect the log.
Scrutinize your deployment for anything that does not follow best practices.
I ran recover on a backup and it detected nothing wrong. Does that mean I should do the same on my working file and continue working with that?
You may need a newer backup copy.
You may need to take your working copy down off the server and not allow people to access while you are doing it. THen recover it. Then open a recent back up copy, save a clone of that back up copy and import all data from the recovered copy into the clone before uploading the new copy created from the clone back to your server.
