Couchbase Server CPU usage increasing alot along with EBS volume size?

Couchbase Server
1

Hi,

I am using Couchbase Server 6.6.0 CE and Syncgate way 2.8.1. I have been observing most of the time CB Server CPU usage reaches 90% and drastically server EBS volume also increasing. How can we find the root cause?

Thanks for your help in advance.
