I'm having an issue creating a XDCR to Elasticsearch. I'm getting the following error on Couchbase: xdcr\_errors.log [xdcr:error,2014-11-04T13:23:14.796,ns\_1@couchbase002:\<0.8335.2272\>:xdc\_vbucket\_rep:terminate:489]Replication (CAPI mode)434c41fc737b38b9a374a08085553abf/adepteo/adepteo ( adepteo/620 -\> http://**_@172.16.2.169:9091/adepteo%2f620 ) failed: {http\_request\_failed,"POST", "[http://adepteo](http://adepteo):_** @172 .16.2.169:9091/adepteo%2f620/\_revs\_diff", {error,{code,503}}} couchdb.log [couchdb:info,2014-11-04T13:04:05.135,ns\_1@couchbase002:\<0.2898.2275\>:couch\_log:info:41]Retrying POST request to [http://adepteo:\*\*\*\*\*@172](http://adepteo:*****@172) [http://adepteo:\*\*\*\*\*@0.0.0.172/](http://adepteo:*****@0.0.0.172/) . 16.2.169:9091/adepteo%2f461/\_revs\_diff in 0.5 seconds due to error {code,503} Couchbase bucket has about 133K items in it, Elastic search gets about 90K. These errors seem to repeat a fill up the logs rapidly. No errors log on Elastic search machine. I am using a custom ES template. Any help is much appreciated.
