In the log, I got a lot of messages like:
Error: [2009-06-03 14:20:09 [ERROR]] Error while processing connection: couldn't read from #<SB-SYS:FD-STREAM for "a socket" {C8B5159}>:
                                                                  Connection reset by peer

Is it something I can eliminate or it's an unavoidable evil of any web server?

Thank you,
Andrei
