Ray, this issue has again popped up and I'm at a loss for how we're ending up in the same boat. We're getting the exact same problem. Making a change to the database via our backend pages freezes the page and kicks 500 errors on any page that utilizes the product table. I don't know if some way in which we're writing to the database is corrupting it. I wouldn't think so, as it's all based on long used webassist code. Have you ever had an issue with a database repeatedly become corrupted? Any ideas on how to troubleshoot would be appreciated.
