On Rocky9 kubernetes worker node, the haproxy external check script times out and doesn't start

Report

I am unable to set up PerconaXtraDBCluster because the haproxy external check script times out.
I confirmed that this problem occurs on Kubernetes worker nodes of Rocky9. This problem doesn't occur on Kubernetes worker nodes of Ubuntu 20.04.
I seem to haproxy happen in busy loop. Because cpu resource is very increase.
Of course, when I run check_pxc.sh within the haproxy pod, I can confirm that it connects to the mysql cluster normally.

I found that this problem happen in Amazon EKS(amazon linux 2023 with kubernetes 1.29).
amazonlinux/amazon-linux-2023#693

Please let me know if we need more informations.
