This can add to server load and slow loading times as it gets scanned every page load.

You also might want to disable mod_unique_id for modsec too. It will prevent that file from growing and being scanned.

Clear the file
yum install ea-modsec-sdbm-util
Should also help keep that file in check if he chooses not to disable it
