Dear All,

 

when we are bootstrapping a new node,we are experiencing high cpu lo= ad which affect the rt ,and we noticed that it's mainly costing on Pending-= range-calculator ,this did not happen before.

We are using C* 2.1.13 in one DC,2.1.18 in another DC.

Could anyone please advise on this?

 

Thanks,
