I am getting problems with a json request.

When i do a index search with GET, i have an error ERROR
Errno::ECONNRESET:
Connection reset by peer @ io_fillbuf. Below is a full log of the
problem.

I have been trying to google the io_fillbuf but i can’t seem to find any
clear answers to what it is.

In my ApplicationController i have “skip_before_action
:verify_authenticity_token” as I am just using rails api for a pure json
app.

Started GET "/api/v1/images.json?type=index&more=yes&offset=80" for
169.254.249.61 at 2014-08-21 10:30:15 Processing by
Api::V1::ImagesController#index as JSON

Parameters: {"type"=>"index", "more"=>"yes", "offset"=>"80"} index

params type index
images length 20
Completed 200 OK in 97ms (Views: 0.1ms | ActiveRecord: 0.0ms)

Is it ok if you type the url into a browser?  If so then it may be to
do with the client app

This means your app is trying to make an external call to another web
server (redis? the database? another external service?) during the web
request.

This is typically a network-layer problem, on Heroku I saw these happen
relatively frequently. When I asked Heroku about it (I actually met with
a support engineer in person to get an answer about this), they said
this was basically one of the costs of doing business on the Amazon
grid.

Essentially, AWS has these little "gremlins" in the cloud -- sometimes
your requests to external services (like other services on the cloud)
simply fail or do not respond. This appears to affect all AWS
applications (I believe it is a network-layer problem)

If this problem is consistent (that is, it happens every time you hit
the URL), then ignore what I said above. If you are on another provider
(not Amazon), I would first figure out what external service your app is
trying to connect to and then follow up with them  to see why the
external service isn't performing consistently.
