Description
Steps to Repro
1. Create a 2 node cluster (.90, .237) with all services on 6.6.3
2. Stop server on .90
3. Upgrade to 6.6.4 on .90
rpm -Uvh couchbase-server-enterprise-6.6.4-9946-centos7.x86_64.rpm
|
4. Try connecting to /pools/default on .90 node .
Results in "unexpected server error, request logged"

looks like ns-server is unable to connect to memcached. Probably this is also why other services like index and query seem to be exiting (as they are unable to make /pools/default requests)
