Description

In a few cases it was observer that replications were crashing with `kaboom` exit. This happens here:

https://github.com/apache/couchdb-couch-replicator/blob/cb41bacb2a06613649df46d62249afebda42b8c0/src/couch_replicator_api_wrap.erl#L236

this is during an open_revs call one of the docs. So change feed found it but then could not get its revisions.

The reason is open_revs get request returns an empty result when more than one nodes are in maintenance mode.
