¿Qué podría estar causando este rails ioerror cerrado flujo?

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 subir archivos a través de un cliente de Java.¿Qué podría estar causando este rails ioerror cerrado flujo?

Si un usuario desea cargar una carpeta, todos los archivos que contiene se cargarán recursivamente. 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 es la traza de la aplicación:

No tengo ni idea de por qué sucede esto ... el cliente puede cargar unos 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!

Creo que lo he descubierto, al menos creo que sí (el cliente simplemente continúa cargando ahora, sin errores). Después de leer los datos de un archivo que cargue, también debe CERRAR. ¿Quien lo hubiera pensado? : P

yo estaría de acuerdo, pero ¿sabe por qué lo que importa? ¿Te estás quedando sin espacio de alguna manera? –

@JosephHolsten ¡Buena pregunta! Me gustaría saber lo mismo! –

Nos encontramos con este mismo problema con nuestra aplicación Rails, aunque el simple hecho de cerrar el archivo no nos funcionó (utilizamos Paperclip y cierra el archivo). Desarrollé un parche de mono para la clase Tempfile que lo ha arreglado para nosotros, y lo usamos como un inicializador de Rails.

lo pueda levantar desde http://github.com/jwinky/ruby_tempfile_ioerror

¡Gracias! Me salvaste mucho tiempo. – weston

Tengo el mismo problema. Usó el parche de mono desde arriba, pero eso no ayudó. ¿Alguna otra idea? –
