> Not sure if this is handled better in procedure based WAL splitting; in any
> case it affects versions before that.
> The problem is not in ZK as such but in internal state tracking in master, it
> seems.

> never resubmitted.
> RS never logs anything else for this task.
> Killing the RS on the worker unblocked the task and some other server did the
> split very quickly, so seems like master doesn't clear the worker name in its
> internal state when hitting the threshold... master never restarted so
> restarting the master might have also cleared it.
> This is extracted from splitlogmanager log messages, note the times.
