database table sam_errors is running full – plugin simple-ad-manager

Hoi!

My Database Table has actually a Size of 31 GB !!!
There are 9,811,208 Entrys !
I recognized that a little bit late – Hope not to late.

What is stored in this Table?
Are they only Error Messages?
Can I easily delete all entrys?

In the Database Cells are Select Statements like this:

SELECT
                  gz_sam_places.id,
                  gz_sam_places.name,
