Ok, so I exterminate the population in Capua when I first conquered it. It was a huge city, so it went down to 4,000 when exterminated, I think. So natural unrest, distance from Antioch (capitol of the Big S), and Culture Penalty means that, regardless of how many pesant units I queue up, maintaining order with new recruits is a difficult proposition.
As far as bringing in peasants from Antioch or whatever, it's hard to keep them within reinforcement distance of your regular army. I put the Peasants in a separate army, because I need all of 20 units in the army to win the major set piece battles against a 20 unit Roman army.
I dunno whether it's bad luck, but it always seems that the Brutii or Scipii manage to attack my peasant army first, my regular army reinforcement fails to materialize, and my peasants withdraw. The Roman armies press their attack during that turn and pwn the peasants.
