其他信息（Additional Information）

未见error 日志，在增量同步时read_count不更新，diff 逐渐变大
查看目的端redis，在shake.toml中配置的地址为redis cluster 的一个节点，该节点在上午10点半左右发生了failover，但当时redis-shake 正常同步，下午14：11分未见异常

问题不好查。首先 redis-shake 没有处理 failover 的场景，理论上出现 failover 就会出错才对。建议你再跑试试，看看没有 failover 的时候是否运行正常。

重跑后正常运行了，想找到什么原因会导致redis-shake这样停止更新的情况？

@sofiajie 我也第一次遇到，你可以打栈看看
