La instalacion se queda colgada

Nuevo usuario
Estoy haciendo mi primera intalacion con Magento y he descargado el archivo, descomprimido en local y subido toda la carpeta al servidor. Chequeo la validez del servidor y me da todo ok, aplico CHMOD 777 a la carpeta de magento en el servidor e inicio la instalacion. Todo va bien hasta que se para y ahi se qeda, luego tengo que esperar varias horas hasta que el servidor me permite volver a intentar la instalacion y se repite el problema. ¿Teneis alguna idea de porque puede ser esto?.

Gracias.

PD. Este es el log de la instalacion hasta que se queda colgada:
