i found, this happens, if the app server is running for longer time(in  
idle status, i guess) and fails to require “require ‘spreadsheet/excel’”  
whenever that controller gets called. but when i restart the server, it  
works fine… can somebody help me fix this issue please? its a bit  
urgent… Thanks in advance.
