移动设备调用Web应用使用RedisSession机制报错ERR DISCARD without MULTI

Question

1.应用web服务是提供给手机访问的，所以网络为无线网络
2.使用的Session机制是redis工具包，多个节点Session配置为共享
import com.ovea.jetty.session.redis.RedisSessionIdManager;
import com.ovea.jetty.session.redis.RedisSessionManager;
3.目前发现移动设备调用该应用，报以下错误后会不断增加报错频率直至无法访问

感谢兄弟姐妹们提供解决方案及宝贵经验，及等回复哦
