Oracle DMS任务在满载时失败

我正在尝试将DMS任务从Oracle运行到AWS PostgreSQL。DMS任务在云监视日志上给出了以下消息错误：

    [SOURCE_UNLOAD ]E: ORA-08103: object no longer exists [1022307] (oracle_endpoint_unload.c:235)'

    [TASK_MANAGER    ]W:  Table 'schema'.'table_name' (subtask 1 thread 0) is suspended'  (replicationtask.c:2468)

我的表有2.2亿条没有主键的记录。验证源表和目标表后，仍有20万条记录等待迁移

想知道之前有没有人遇到过同样的问题。如果有人分享解决问题的经验。将不胜感激
