URL: https://github.com/apache/couchdb/issues/3988
## Description
I have found a problem in our Couch cluster that some of the continuous
replication jobs are still running (showing under _active_tasks); however, the
corresponding replication doc is no longer in _replicator.
These continuous replications were setup between 2 clusters, cluster xxx
with 4 nodes and yyy with 2 nodes.
Currently I could not find a way to stop these tasks, and they are still
around after Couch service restarts.
See example below.
```
