So, I was investigating a new feature in the QC admin panel called 'QC Sense' after I (foolishly)tried running the report(it's just a report, it can't hurt anything...right?), our server slowed down to a crawl to the point users could no longer log in. I just stopped and restarted the QC service, and the issue seems to have resolved.
My question is, do I have to do anything else to make sure this report won't run again, or was the proccess of stopping and restaring the QC service enough?

Thank you in advance,
Mike F
