Subject: error catching question:

I have some code that checks a pop3 email box for me.  It is wrapped in a
begin/rescue clause.  However, somehow it seems to have escaped the rescue
clause:

/usr/lib/ruby/1.8/net/protocol.rb:197:in `rbuf_fill': socket read timeout
(60 sec) (Timeout::Error)
        from /usr/lib/ruby/1.8/net/protocol.rb:160:in `readuntil'
        from /usr/lib/ruby/1.8/net/protocol.rb:178:in `each_message_chunk'
        from /usr/lib/ruby/1.8/net/pop.rb:791:in `retr'
        from /usr/lib/ruby/1.8/net/pop.rb:789:in `critical'
        from /usr/lib/ruby/1.8/net/pop.rb:792:in `retr'
        from /usr/lib/ruby/1.8/net/pop.rb:648:in `pop'
        from fido.rb:33:in `checkNewRequests'
        from fido.rb:31:in `each'
        from /usr/lib/ruby/1.8/net/pop.rb:517:in `each'
        from fido.rb:31:in `checkNewRequests'
        from fido.rb:30:in `start'
        from /usr/lib/ruby/1.8/net/pop.rb:323:in `start'
        from fido.rb:30:in `checkNewRequests'
        from fido.rb:20:in `start'
        from fido.rb:161

Here's the code:

def checkNewRequests()
        begin
            Net::POP3.start("mta.algx.net", 110, "blah", "passblah") { |pop|
                pop.each { |msg|
                    puts "Checking msg #{msg.id}" if DEBUG
                    if msg.pop =~ /Subject: [fF]ido/
                        if msg.pop =~ /--reload--/
                            printInfo("Agent reload requested")
                            loadAgents()
                            msg.delete
                        else # process request
                            mailMsg = MailMsg.new(msg)
                            request = Request.new(mailMsg.agentList)
                            success = request.doAgents
                            printInfo("Success = #{success}")
                            if success
                                printInfo("Sending response to
#{mailMsg.from}")
                                sendEmail(mailMsg.from, request.getResponse)
                                msg.delete
                            end
                        end
                    end
                }
            }
        rescue
            printInfo("Problem checking email...retrying in 30 seconds")
            sleep 30
        end
    end




Any ideas why the begin/rescue didn't catch it?

Thanks,.
