CIS is placing errors in the dberr.txt log under directory C:\WINDOWS\system32\CatRoot2 mostly during a boot, but at other times too for some users. There is a rather long thread concerning this, concluding about here:

I think there have been some honest efforts to discern the cause of these errors and would like to know if the Comodo developers consider this a problem or not. Thanks.
