Hello,

Im using the following amazon web service API for S3 :

[http://amazon.rubyforge.org/](http://amazon.rubyforge.org/)

The problem is that after I establish a connection using  
establish\_connection!, and try using the “store” command, I keep getting  
the following error. However, if I reboot my webrick server, it works  
fine for about one hour and then starts throwing this error:

Errno::EINVAL in UsersController#upload\_pic

Invalid argument

RAILS\_ROOT: ./script/…/config/…

Does anyone know why this could be?

hey have you ever found the solution? i think i have the same problem  
even on my production server. ive read around google that there may be a  
bug in ruby about handling timeouts/header information.
