Not a limit on respawn, but "limiting" the respawn of certain enemies that can be used to farm souls. For example, if you kill a certain enemy, go back to the bonfire and repeat over and over it will result ion the enemy disappearing from the game. Not that if you kill all the enemies over and over it will get to the point that there will be no more enemies. Or at least that's how I understand that particular mechanic.

Happened to me with a Hollow Soldier that I alwas killed after teleporting to the bonfire in the Cardinal Tower.
