I keep seeing errors in my logs similar to the below.

Can anyone suggest why I could be getting such an error intermittently? Is it a caching issue?

Every time I attempt to load the about-us page it loads perfectly but every few days there's an error like this in my logs but it's not confined to a single page. Sometimes it's the homepage, some times it's other pages. 

Started GET "/about-us" for xxx.xxx.xxx.xxx at 2014-08-16 07:54:06 +0100
Processing by PagesController#about as */*;q=0.6
Geokit is using the domain: mydomain.com
[1m[35mPage Load (0.2ms)[0m  SELECT `pages`.* FROM `pages` WHERE `pages`.`name` = 'About Us' LIMIT 1
Completed 500 Internal Server Error in 2ms

ActionView::MissingTemplate (Missing template pages/about, application/about with {:handlers=>[:erb, :builder, :arb], :formats=>["*/*;q=0.6"], :locale=>[:en, :en]}. Searched in:
* "/var/www/myapp/releases/201408150651/app/views"
* "/var/lib/ruby-rvm/gems/ruby-1.9.2-p320/gems/activeadmin-0.3.2/app/views"
* "/var/lib/ruby-rvm/gems/ruby-1.9.2-p320/gems/kaminari-0.12.4/app/views"
* "/var/lib/ruby-rvm/gems/ruby-1.9.2-p320/gems/devise-1.4.7/app/views"
):

This question is similar to: Random rails ActionView::MissingTemplate errors so this is happening to other people but there's no defined answer there either.

You can't prevent this error as there are load reasons(like you mentioned missing cache, unknown request format and etc)

You can try to restrict the number of predefined formats like:

get '/about-us' => 'controller#about', :format => /(?:|html|json)/

Also you can suppress this exception. Create a new file(for example exception_handler.rb) in the directory config/initializers and Add this line into created file: 

ActionDispatch::ExceptionWrapper.rescue_responses.merge! 'ActionView::MissingTemplate' => :not_found

Hope it helps.

@ProblemSolvers is a possible solution. However, I added the following method in my application_controller.rb file so that such errors will render a 404 page rather failing with a error message on screen 

rescue_from ActionView::MissingTemplate, :with => :rescue_not_found
protected
def rescue_not_found
  Rails.logger.warn "Redirect to 404, Error: ActionView::MissingTemplate"
  redirect_to '/404' #or your 404 page
end

you can wrap this code in a if statement, something like this if Rails.env.production? given that the env is setup so your dev environment wont be affected
