Normally it is better from a solver point of view (to avoid this error), to apply remote displacements instead of forces and restrain say the rotation say in z (about axis of pin) to prevent that and push it up or down in the direction of the force.To get the force applied then we just look at the reaction (remote. displ.).&lt;\/p&gt;&lt;p&gt;If one does not want to use the above, we can move the pins closer to the edge of the hole since there is no point in resolving the movement across the gap which is a rigid body movement and use adjust to touch in the contact settings.
