unity20192.5f1, Physics.Linecast could not hit the rigidbody+collider?

An object has rigidbody and Capsule Collider and Animator. When rigidbody. isKinematic is false, it is often not hit（Physics.Linecast(startPosition, endPosition, out hitInfo)）, I've seen the ray passing through Capsule Collider through "Debug.DrawLine", and if it is true, it is easy to hit.



Why is this?
