A problem maybe caused by Rocky in mysql

Hello everyone,

I have a k8s cluster’s OS-IMAGE contains both Rocky Linux 9.2( KERNEL-VERSION: 5.14.0-284.11.1.el9_2.x86_64) and Centos 7(KERNEL-VERSION: 3.10.0-1160.el7.x86_64), when I’ve installed a helm chart which has a statefulset(nacos-0, nacos-1, nacos-2) and a deployment(nacos-mysql), the statefulset is running well but mysql takes 16Gi memory usage when mysql pod scheduled on my Rocky Linux 9.2 Node, when this mysql pod was scheduled on my Centos 7 Node, it only takes 200Mi a memory usage.
on Rocky Linux 9.2 Node:
on Centos 7 Node:
NAME CPU(cores) MEMORY(bytes)
nacos-mysql-5b9787c745-rc49s 2m 187Mi

Could anyone explain why?

Thanks in advance!
