Here is a minimal example to study the behavior. The sketch has an external geometry to a Part point that lays 0.01 nm away from the Y-axis. An arc that has a coincidence constraint to this point and a tangent constraint to the Y-axis is frozen and can not be moved anymore. Tolerance values in this magnitude may happen for external geometries.

May be connected with inter line tangency as described in this forum post.
