i’ve installed spreadsheet(0.6.4.1) and required it in one of my
controllers. it works fine for some days and suddenly starts giving
“Input/output error”.

/usr/lib/ruby/gems/1.8/gems/spreadsheet-0.6.4.1/lib/spreadsheet/excel.rb:3:in
write' /usr/lib/ruby/gems/1.8/gems/spreadsheet-0.6.4.1/lib/spreadsheet/excel.rb:3:inwarn’

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.
