8455	Lack of filesystem permissions to save uploaded file results in server hang	Carl Meyer	nobody	"If the web server user does not have filesystem permissions to write to the ""upload_to"" directory of a FileField or ImageField, attempting to upload a file results in the server process hanging and eating 100% CPU.  

Instead, there should be a 500 error or debug page with a sensible error message.

This issue seems to exist ever since file-storage-refactor.  I can replicate it on both the Django development server and Apache 2.2 on Debian Linux.

I believe the problem is that django.core.file.storage.FileSystemStorage._save() makes unwarranted assumptions about the reason for an OSError, causing an infinite loop, as outlined by rajeshdhawan in [http://code.djangoproject.com/ticket/8203#comment:7 this comment] on #8203."		closed	File uploads/storage	dev		fixed			Accepted	1	0	0	0	0	0
