Re: Amazon + Django each 12 hours appears that [Errno 5] Input/output error

Are you deploy your EC2 django instance in debug mode ?

For me this the reference for deploy http://michal.karzynski.pl/blog/2013/06/09/django-nginx-gunicorn-virtualenv-supervisor/.

At the end in the line 50 is referenced a get_context_data() function which is inside of a class based view that inherit of TemplateView CBV
but in my console the server require restart and when I did this, the error was solved of a magic way ..

In addition I had this error yesterday, I restart my server, and today I have again the error.
There is some problem with EC2 infraestructure with Django (I don't think so) or the problem is more for my application side?
I don't think so that the function get_context_data() of my application be the problem ...

I recently setup and deploy an Amazon EC2 instance for deploy my django project.

I've search this error and I found this ticket reported https://code.djangoproject.com/ticket/23284

This report is very similar to my error ...
Although I don't know if this error back inside 12 hours, I restart my server and this was solved and now all it's work O.K.

When one bug is declared as invalid in Django
What does it mean?
