Queue dies with unexpected output

Hi, I have a queue server script written using POE::Session. The queue server dies with a weird return value and this behavior is not predictable. The expected output of the url sent to the queue is always '1'. But sometimes the following Http::Response is received (unexpected output) Wrong response: HTTP/1.1 200 OK Cache-Control: private Connection: close Date: Fri, 18 Jun 2010 11:19:33 GMT Content-Encoding: gzip Content-Type: text/plain;charset=utf-8 P3P: policyref="/w3c/p3p.xml", CP="CAO DSP COR CUR ADM DEV TAI PSA PSD IVAi IVDi CONi TELo OTPi OUR DELi SAMi OTRi UNRi PUBi IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE GOV" 2???? =================================== Successful Http::Response: Cache-Control: private Connection: close Date: Mon, 21 Jun 2010 11:20:12 GMT Content-Encoding: gzip Content-Type: text/plain;charset=utf-8 P3P: policyref="/w3c/p3p.xml", CP="CAO DSP COR CUR ADM DEV TAI PSA PSD IVAi IVDi CONi TELo OTPi OUR DELi SAMi OTRi UNRi PUBi IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE GOV" 1 =================================== The code Snippet: (where queue waits for the response)
POE::Session->create ( inline_states => { _start => sub { my ( $kernel, $heap ) = @_[ KERNEL, HEAP ]; # Post a request to the HTTP user agent component. When the # component has an answer (positive or negative), it will # send back a "got_response" event with an HTTP::Response # object. $heap->{www_time_start} = [gettimeofday]; $kernel->post( "BY-ua" => request => got_response => GET $url ); $self->queue_stats("enqueue", $url); }, # A response has arrived. Display it. got_response => sub { my ( $heap, $request_packet, $response_packet ) = @_[ HEAP, ARG0, ARG1 ]; my $http_request = $request_packet->[0]; my $http_response = $response_packet->[0]; my $iv = tv_interval ($heap->{www_time_start}); my $url_iv = sprintf "%s=%.2f", substr($http_request->url(), -10), $iv; DEBUG "Response time: $iv"; # Make the response presentable, and display it. DEBUG "Received result for ", $http_request->url(), ": ", $http_response->as_string(); }, ); Any pointers on how to resolve this issue ? Thanks
