Tengo una aplicación de rieles, que se ejecuta en modo de desarrollo (con una base de datos sqlite). El propósito de la aplicación es permitir a los usuarios cargar archivos a través de un cliente java.

Si un usuario desea cargar una carpeta, todos los archivos que contiene se cargarán de forma recursiva. Si un usuario desea cargar un archivo, el archivo se cargará normalmente.

Aquí está el error que estoy recibiendo:

 IOError

    in UploadedFilesController#new

closed stream

Aquí está el seguimiento de la aplicación:

No tengo idea de por qué sucede esto ... el cliente puede cargar aproximadamente 15-30 archivos (desde una carpeta, a través del cliente java) antes de que aparezca este error. Estoy ejecutando Rails 2.0.2. ¿Podría el hecho de que estoy ejecutando en modo de desarrollo usando sqlite como base de datos causar esto? Cualquier ayuda sería muy apreciada!

Gracias chicos
