Environment:

OS : Fedora CoreOS 35.20220327.3.0
Kernel : 5.16.16-200.fc35.x86_64
Cloud provider or hardware configuration: Dell FC640/MX740c
Rook version: 1.8.8/1.9.0
Storage backend version : 16.2.7
Kubernetes version : 1.23.5
Kubernetes cluster type: Baremetal (self-managed/vanilla)
Storage backend status : Keeps timings out when mons are crashing and updated with number of mons down

Create 3 mons normally, check the mon node process after initialization, you will find that ms_dispatch and fn_monstore will have cpu 100% problem, and pg pool is being created at this time. Quickly kill these two processes ceph cluster is normal.
