I had a dwarf child go into a strange mood and claim a craftsdwarf's workshop. No big deal.
I check back on him later, and see that he's gathering a lot of wood. At about 50 wood, I started to wonder what was going on. Oh, he'll probably hit some magic limit to dwarven enthusiasm. After 100 wood, with no idea what was up, I checked the wiki and forums.
After reading about
http://dwarffortresswiki.org/index.php/Planepacked I took him out of his burrow. I have all children and babies in a burrow that keeps them away from really dangerous areas, like outside the city walls and deep underground. He had access to all the materials he wanted, but being in the burrow made him gather wood endlessly. When free of the burrow, he started to gather other materials.
By the time I figured it out, he had gathered 252 logs. Then he proceeded to add: goose leather, vulture leather, giant earthworm leather, rough pyrites, limonite gizzard stones and turkey leather.
