canal error

您好！ 在使用otter(v4.2.15)单向mysql同步时，开始是正常的，跑了十几个小时后，canal出现以下报错信息，请问如何解决？ pid:1 nid:1 exception:canal:34->88:com.alibaba.otter.canal.parse.exception.CanalParseException: com.alibaba.otter.canal.parse.exception.CanalParseException: parse row data failed. Caused by: com.alibaba.otter.canal.parse.exception.CanalParseException: parse row data failed.
