City randomly starts producing Settlers.

I didn't have auto on, and I had a long queue of units for protection. I am assuming that my Iron supply was cut off, so it couldn't produce Spearmen or Axemen anymore, but why start producing a Settler?

Were Settlers part of your queue?.. it could have just started skipping the units it couldn't build.

My most recent pre-Warlords game also randomly produced settlers, twice, towards the end of the game. They weren't queued up, and I had not lost a resource -- it's possible that a unit being built was obsoleted by a tech, but usually that just converts to the upgrade.... I didn't notice till the settler was produced, unfortunately, so didn't have a before and after save.

Are you sure you didn't receive a "Our Empire needs to grow we should build a settler!" message and accidentally clicked "Build one at the next opportunity"?

It was not queued, and advisor suggestions were off.
