---------------------------------------
Summary: replication crashes
Key: COUCHDB-2484
URL: https://issues.apache.org/jira/browse/COUCHDB-2484
Project: CouchDB
Issue Type: Bug
Security Level: public (Regular issues)
Reporter: Gunther Gruber
We are Using Couchdb Version 1.6 with 8.3T of data, biggest Database ist 2.1T.
At this moment we switch to new hardware with more storage space. We copied
the files with rsync and started the replication.
One system is already in sync, the other is doing the replication.
I appreciate that besides the errors in the log, the first system is now in
sync.
The log looks like the following
Retrying POST request to http://replication:XXXX/database/_revs_diff in 0.5
seconds due to error req_timedout
and then

It seems to me like a timeout and the replication task then exits. I allready
played arround with the configuration setting with no succes. I can provide
more information if needed.
