Subject Re: Understanding a couple replication errors
Date Wed, 02 Aug 2017 12:40:39 GMT
Hi Joan, many thanks for your reply

Why would the timeout and closed connections happen? I see it quite often
on the logs TBH but also, a slightly different one is a timeout against the
cluster itself. What may this mean?

[error] 2017-08-02T12:38:27.321697Z couchdb@couch-2 <0.7114.568> --------
Replicator, request PUT to "http://admin:*****@
127.0.0.1:5984/my_db/35e78fe9d421677c77dea34522de2b99?new_edits=false"
failed due to error {error,{conn_failed,{error,etimedout}}}

Regards
