Subject [jira] [Created] (COUCHDB-1427) Kept trying to run erratic replications half an hour after I'd deleted their docs from _replicator

Kept trying to run erratic replications half an hour after I'd deleted their docs from _replicator
--------------------------------------------------------------------------------------------------

                 Key: COUCHDB-1427
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1427
             Project: CouchDB
          Issue Type: Bug
          Components: Futon, Replication
    Affects Versions: 1.1.1
         Environment: Windows 7 / 64bit
            Reporter: Kurt Milam
            Priority: Minor


Note: I did all of the following via the Futon interface on my local development PC:

1. I added a doc with continuous=true and a user-defined ID to _replicator and created a new,
empty target database.
2. I realized shortly thereafter that my doc had an error.
2. I deleted the doc (after first being unable to edit/correct it) and deleted the target
database
3. I repaired and recreated the doc, using the same ID as in step #1, and I created a new,
empty target database
4. I probably did this a total of 4 times before I got the doc right (it was my first replication
doc working with a filter)
5. 10 minutes after I'd deleted the erratic docs, Couch was still trying to run the replications
6. I deleted the correct doc, which had sparked a successful replication
7. Half an hour later, Couch was still trying to run all of the unsuccessful replications,
logging errors at the rate of around 20K lines per minute
8. I finally restarted Couch - after it came back up, it no longer tried to run the replications


Following are a few representative log entries:
