How can i find the reason of CPU usage in couchbase

In my docker desktop i have CB server with version 6.6.1. Docker desktop shows that CB container always uses CPU even there is no any workload on the CB. No index operation, no query etc… See the gif i send, whene there is no op in CB monitor, you can see the container’s CPU usage in so high.


When I terminal into container and run top, i see that indexer and beam.smp uses the CPU.
There is no operation on the CB. So the indexes don’t need to change.
And i don’t know what beam.smp does.
When there is no work i use my most of my CPU. Is this because of CB requires too much CPU?
In CB shouldn’t i use GSI and only use KV?
