回退版本至 2.10.6 后，继续运行 python migrate.py。数据迁移成功。为何迁移了数据库 0 下的健的总数：53，原因在于自建 Redis 中的数据在变化中所导致。 0

在 bash sleep 60 秒 的情况下，很难出现并发锁定的情况。或者增加更多的容器，或者提升执行命令行的频率。设置 bash sleep 10 秒。已经出现并发锁定(防止同一个租户下的用户同步同时在多个容器中执行)的情况。当部署为集群时，已经可以保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。理论上的计算公式，一个租户的同步时间间隔为：4 / 3 * 10 = 13，结果单位为秒。符合设计预期。总结：部署的容器数量不要超过租户的数量，以防止并发锁定的情况过于频繁。 0

由于 Supervisor 仅启动 1 个 queue/listen，因此，一旦某一队列处于 reserved，则其他队列只好一直处于 waiting 状态，所以，临时决定 remove 命令删除作业，以启动程序的继续正常运转，查看 log 表，其 message 字段内容，可以确定队列 ID 值为：159，info 命令打印关于队列状态的信息时，reserved 状态的队列数量减少 1，done 状态的队列数量增加 1，符合预期 0
