Jpos java.net.SocketException

如何解决Jpos java.net.SocketException

我编写了一个部署在 tomcat 上的基本 jpos 客户端应用程序，它向 jpos 服务器发送 8583 条消息。 jpos 服务器实现已经运行了很长时间，并且有其他客户端连接到它。我写的客户端 jpos 应用程序是由一个休息端点触发的，当请求串行执行时它工作正常。当通过运行多个线程增加负载时，我在日志中看到以下异常。知道在这种情况下会发生什么吗？

代码

class jposClient{

private CSChannel csChannel;

public ISOMsg send(ISOMsg request){
ISOMsg response
csChannel=getCSChannel();
csChannel.connect();
jposChannel.send(request);
do {
    response = jposChannel.receive();
    }while(response.getMTI().startsWith("08"));

}

return response;

}

private CSChannel getCSChannel() throws IOException {
    
        if(csChannel!=null){
return csChannel;
}
        try {
            csChannel = new CSChannel();
            Configuration configuration = new SimpleConfiguration();
            configuration.put("keep-alive","true");
            configuration.put("expect-keep-alive","true");
            configuration.put("host","127.0.0.1");
            configuration.put("port",String.valueOf(5456));
            csChannel.setConfiguration(configuration);
            csChannel.setPackager(new GenericPackager(
                "packager.xml"););
        } catch (ISOException e) {
            e.printstacktrace();
        }
        return csChannel;
    }

}
