bdr appears to be trying to replicate to itself

I noticed a very strange issue starting about 20 days ago and my pg_xlog has just been filling up since then.

```
HOST A:
postgres=# select * from pg_replication_slots;
                slot_name                | plugin | slot_type | datoid | database  | active | xmin | catalog_xmin |
restart_lsn

SELECT     slot_name, database, active,     pg_xlog_location_diff(pg_current_xlog_insert_location(), restart_lsn) AS
retained_bytes FROM pg_replication_slots WHERE plugin = 'bdr'; 
                slot_name                | database  | active | retained_bytes
-----------------------------------------+-----------+--------+----------------

(2 rows)
```

HOST B:

```
select * from pg_replication_slots;
                slot_name                | plugin | slot_type | datoid | database  | active | xmin | catalog_xmin |

select bdr.bdr_get_local_nodeid();
     bdr_get_local_nodeid
-------------------------------
 (6188733518371128845,2,16385)

SELECT     slot_name, database, active,     pg_xlog_location_diff(pg_current_xlog_insert_location(), restart_lsn) AS
retained_bytes FROM pg_replication_slots WHERE plugin = 'bdr'; 
                slot_name                | database  | active | retained_bytes
-----------------------------------------+-----------+--------+----------------
 bdr_16385_6188730679935789649_1_16385__ | database_name | t      |          68736
```

So it almost looks like HOST A is trying to replicate to itself since the replication_slots has the same node_id of
itselfand it's just filling up the pg_xlog. 

This server has been setup since mid-may and I haven't added any new nodes but I did upgrade just this past weekend
beforeI noticed there was a problem: 
dpkg -l | grep '^ii' | grep postgre

Before I was on postgresql-bdr-client-9.4           9.4.4-1trusty

Can anyone help me fix this? I'm running out of HD space.

Thanks!
