TaskFailedException : A task was canceled.

We are seeing that our Tasks are getting cancelled with the exception below. We are suspecting DTF is cancelling long running Tasks and in all the instances of below exception , we have seen the Task running for 2 mins or so. Is there any configuration for Task cancellation in DTF ? This Task succeeds on retrying.

Env : Service Fabric Service running on 10 nodes.
