[Ruby] Server Inconsistencies

[Jordan Isip]

Hi All,

I'm having a bit of an issue that is hard to debug since it only occurs on my production server and not on my localhost.  About half the time on my production server I get the following error on an instance variable defined within my controller.  

ActionView::TemplateError (undefined method `[]' for nil:NilClass) on line #38:
<%= @total_points[caption.id] %>

Then if I hit 'refresh', it will work normally again. I would say this error comes up about 30% of the time.  Any ideas on why there would be inconsistencies between the two difference servers?

Thanks in advance for your help.
