Errno::ENXIO in Login#index

Hi ROR riders’

I’ve some apps working with rails and I got the following error when I
tried to log-in.

Errno::ENXIO in Login#index
Device not configured

The app works, but I cannot make a Login. I’ve re-started the mongrel
server and the app is working again, but after some logins and logouts
and adding data to the app, I got that error.

Does anyone knows what produces such error?

Thanks a lot,
