El archivo temporal en upload de archivos se borra

[SeaPirates]

Hola, tengo un problema al subir archivos pesados a mi servidor 700mb- 1,5GB.

Como están mucho rato por alguna razón el archivo temporal se borra, o cambia de nombre y cuando finaliza da error de que no se encontró el archivo temporal.

¿Que puede ser y que solución puede haber?
