I am using Ruby 1.8.2 on WinXP and am receiving a “Marshal Data Too  
Short” error. I havent been able to repeat the error as it seems to  
happen randomly in my rails program. However, the version of Ruby I’m  
using already has the file.binmode lines outlined in:  
[Peak Obsession](http://wiki.rubyonrails.com/rails/pages/MarshalDataTooShort).

If possible I’d like to avoid switching to active record store since  
this app does not currently use a DB. Any help/suggestions would be  
greatly appreciated.

Thanks,  
Eran
