TSocket: Could not connect to ...(Connection timed out [110])

[JKnight JKnight <be...@gmail.com>]

Dear all,
I use Java to implement Thrift server and use PHP for client.

Here is the server code:
        TNonblockingServerSocket socket = new TNonblockingServerSocket(
                listenPort);
        THsHaServer.Options options = new THsHaServer.Options();
        options.minWorkerThreads = 64;
        TServer serverEngine = new THsHaServer(processor, socket, options);

Here is client code:
        $this->socket = new TSocket($this->_host, $this->_port);
        $this->socket->setSendTimeout($this->_sendTimeOut);
        $this->socket->setRecvTimeout($this->_recvTimeOut);
        $this->transport = new TFramedTransport($this->socket);
        $this->protocol = new TBinaryProtocol($this->transport);
        $this->client = new AppServiceClient($this->protocol);

    function openTransport(){
        if(!$this->transport->IsOpen()){
            $this->transport->open();
        }
    }

    function closeTransport(){
        if($this->transport->IsOpen()){
            $this->transport->close();
        }
    }
    public function get_app($id)
    {
        try
        {
            $this->openTransport();
            $data = $this->client->get_app($id);
        }
        catch (Exception $e)
        {
            $this->logs($e->getMessage());
            $this->closeTransport();
            return array ();
        }
        return $data;
    }
    private function logs($log){
        $datetime = (float) array_sum(explode(' ',microtime()));
        file_put_contents("logs/data.txt", date('Y-m-d
H:i:s')."\t".$datetime."\t".$log."\n", FILE_APPEND);
    }
When I trace PHP log, I found the error:
TSocket: Could not connect to ... (Connection timed out [110])
This error occurs once per second.

No error in Java server.

Could you help me to fix this problem?
Thank a lot for support.
