opt/couchbase/bin/projector terminated: signal: aborted (core dumped)

I have created a cluster w/ KV only nodes ( attached screenshot for service description)

On a cluster reboot, I noticed the Projector process restarted w/ a core-dump.
No other process exhibited likewise restart.

Also, output from projector shows a panic w/ cbq-engine connection - Wondering why does it try this when there is no Query component associated w/ any node on the cluster.
