We Recently started seeing this message for 2 of our DCs EventData has more than 2GB so need to disable eventcollection

In addition to this message the ADAuditPLus server appears to be consistently bogged down, CPU wise. 

We have two DCs in the domain that are generating this error in the ADudit website.

When I look at the adaudit \ eventdata folders problem on the Domain Controllers the error is correct, there are 3.3 gb of files on one, and 7.4 gb on the other.

Is there a way to remove the 2gb cap, or a way to force these servers to sync?
