Couchbase beam.smp eating CPU Usage

Having a trouble with Couchbase servers everyday getting too many CPU Utilization Alerts. we checked all the config twice and twice but no solutions.
I get into the Instance and Looked into what causing the CPU Utilization more and I found that “Beam.smp” is eating too much CPU Usage .
Right now I don’t have any Idea to do…

Can anybody help me out that would be Appreciated
