Xcdr replication causing goxcdr to restart

Hey guys,

Over the past week we have been experiencing issues where our xcdr replication to elastic search has become significantly slow and has caused the goxcdr to restart. Sometimes the memory of the 3 couchbase node increases quite signficantly and has caused one node to crash because it has ran out of memory. Here is the logs related to this

Service 'goxdcr' exited with status 1. Restarting.

my settings for the xcdr are as follows:

We also notice that on the xdcr it was encountering additional errors such as:

I tried looking up to see what this means but I cannot seem to find any answers related to this problem. I was wondering if anyone has any insight into what may be the issue here?

Hi Andrew, what versions of Couchbase Server, Elasticsearch, and Elasticsearch Transport Plugin are you using? Best, -Will

Hey @WillGardella, my Couchbase is 4.5, elasticsearch 1.7.5 and my transport is 2.1.1
