Hi @dony.thomas,

What version of Couchbase Server are you running? And are you on Sync Gateway 2.1.0 or another 2.1 version?

We’re using Couchbase Enterprise Edition 6.0.0 build 1693 & Couchbase Sync Gateway 2.1

I think you might be hitting the bug mentioned here: https://issues.couchbase.com/browse/MB-32120

This was fixed in Couchbase Server 6.0.1, but we had some important fixes in 6.0.2 as well which you might be interested in upgrading to: https://docs.couchbase.com/server/6.0/release-notes/relnotes.html
