These messages have appeared before, but not in such numbers. After update log grows by 1GB in hours.
Can we solve problem that causes them?
Also we have huge network traffic on that CH nodes after update

we try update to 21.2.2.8 but nothing changes

      * 2. From the `queue` directory of one of the replicas.
      *
      * The problem is that the numbers (`sequential` node) of the queue elements in `log` and in `queue` do not match.
      * (And the numbers of the same log element for different replicas do not match in the `queue`.)
      *
      * Therefore, you should consider these cases separately.
