Estoy llamando a una lista de urls del mismo dominio y devolviendo un recorte de su html para unos pocos miles de dominios, pero estoy recibiendo este error de aproximadamente 1.000 filas o menos.

¿Hay algo que pueda hacer para evitar este error?¿Tiene sentido crear un paso de espera después de cada fila? cada pocos cientos de filas?

¿Hay una mejor manera de evitar esto?
