How to cancel aggregation for IdentityNow source

For SaaS Connectivity connector (I have build and deployed to my tenant): how do I cancel aggregation process. I have tried using Cancel (X) button in Source UI and it shows as Terminated but when I tail logs (sail conn logs tail) I see that aggregation still running. Based on my logs observation it never stops and runs till completion.
