Unable to add data to text index

Recently, I’ve been getting an error message like in the screen below on every data source. Could someone explain why I’m getting it and what it means?


Thank you

Are there any error messages in your case log file?

I managed to solve the problem. The issue was related to the faulty operation of the SSD where the case was being saved. The drive was malfunctioning even though SMART indicated that the disk was in good condition.
