Question

My Rails action stops rendering the response after the same amount of data transmitted. No error or warning is shown.

At first, I thought that my partial could be a cause of that but then I removed the partial call and inserted some plain text instead and the result html was still getting chopped depending on how much text I insert.

I tried it with thin, webrick and pow + nginx.

It looks as if it had some kind of response size limit somewhere. Any ideas?

UPDATE:

The render fails on the particular code (even if I empty the _offer partial):

# Controller:
@offers = Offer.all

# View:
<% offers.each do |offer| %>
<%= render offer %>
<% end %>

# views/offers/_offer.html.haml
%li{ :class => offer.promo_type }
.content_card
    .content_item_wrapper
        .exclusive_content_ribbon
        .exlusive_glossy
        .exclusive_operator
            .operator_icon
        .exclusive_content_photo= image_tag offer.package.hotel.main_image_path
        .exclusive_content_hotel
            .ex_hotel_stars
                %span{ :class => ["ex_hotel_stars_b", "star_#{offer.package.hotel.stars}"] }
            .ex_hotel_name
                %a= offer.package.hotel.name
            .ex_hotel_place
                %span.ex_hotel_place_country= offer.package.hotel.country.name_ru
                &#8250;
                %span.ex_hotel_place_region= offer.package.hotel.city.name_ru

UPDATE 2:

It starts working if I remove everything below .exclusive_content_photo= image_tag offer.package.hotel.main_image_path (incl. this line)

UPDATE 3:

Any call to offer.package causes it to crash. In console everything works fine.

Bullet gem was the cause of it. For more information see https://github.com/rails/rails/issues/8283
