We have two hosts, host A and host B.
We created an empty database named "my_couch_db" on each host.
We configured a continuous replication on host A where source is "my_couch_db" and target is "http://host.B/my_couch_db".
When adding documents on host A, they are replicated to database on host B, but after a few hours the replication crashed and then couchdb too.
The replication stopped after replicating 30231 documents on my_couch_db of host B.
