Hi, even tho this question is little old, I had the same SearchDir warning and couldn't find something helpful. I solved the problem now and I hope I can help other people by sharing my solution:

probably you're tf to scanmatch is too slow (static_transform_publisher x y z yaw pitch roll frame_id child_frame_id period_in_ms) and you simply have to set a lower value for period_in_ms than before, e.g.

<node pkg="tf" type="static_transform_publisher" name="map_scanmatcher_broadcaster" args="0 0 0 0 0 0 map scanmatcher_frame 5"/>
