We have cases when the couchbase nodes start to consume 100% CPU. Usually it due to compaction but rebalance does it too.
This causes a connection close and server fails (and after few minutes come back a live).
Is there a way to configure couchbase to use less CPU?
We are running a couchbase 3 cluster of 4 r3.large ec2 instances with general purpose EBS attached to it as the data path.
