100% CPU usage with Java TNonBlockingServer and THsHaServer

[Kanzhe Jiang]

I wrote a simple packetstreamer thrift server with NBlocking and THsHa server.
The server takes 100% CPU usage in top even when no client is present.

Here is how the server is instantiated:

    public static void simple(PacketStreamer.Processor processor) {
        try {    
            // Use this for a multithreaded server
            TNonblockingServerTransport serverTransport = new 
TNonblockingServerSocket(port);
            TNonblockingServer.Args args = new 
TNonblockingServer.Args(serverTransport);
            //THsHaServer.Args args = new THsHaServer.Args(serverTransport);
            args.processor(processor);
            args.transportFactory(new TFramedTransport.Factory());
            args.protocolFactory(new TBinaryProtocol.Factory(true, true));
            //TServer server = new TThreadPoolServer(args);
            TServer server = new TNonblockingServer(args);
            //TServer server = new THsHaServer(args);
                
            log.debug("Starting the packetstreamer server on port {} ...", 
port);
            server.serve();
        } catch (Exception e) {
            e.printStackTrace();
        }       
    }       

The JConsole profiler showed at least the poller thread with increasing cputime.
The point of using NonBlockingServer is to be graceful with CPU.

Any help is greatly appreciated!
