System becomes unresponsive after upgrading to Rocky linux 9.4

This issue is on Rocky linux version 9.4

On a Rocky linux 9.3 system, I ran yum update to upgrade to 9.4. Then I shut down the system, start it again. The system boots up ok to new version 9.4, but after about 10 seconds, the system CPU jumped almost 100% and the system becomes unresponsive. Cannot SSH connect to the unresponsive system either.

Hardware: VMware Virtual Machine running on Hypervisor VMware ESXi 6.7, Model ProLiant DL380 Gen10.
Processor: Intel(R) Xeon(R) Gold 6238R CPU @ 2.20GHz
Guest OS setting: CentOS 8 (64-bit) (no version 9 available on this VMware version yet), 1 vCPU, 4 GB Memory
Guest Software installation: Server with Graphical UI
Compatibility: ESXi 6.7 Update 2 and later (VM version 15)

The guest is installed with Crowdstrike sensor software for RHEL 9. It is also configured for centralized directory server (directory server running Rocky 9.3) authentication via PAM. An Apache web server is also installed. No other special software running on the Guest.

Prior to Rocky linux 9.3, everything works great. The issue only happens on Rocky linux 9.4 version.

We want to know if this issue is related to hardware or software environment or is it the version 9.4 issue?



You will need to disable crowdstrike or update it to a “fixed” version (if it even exists). If there are no updates but disabling it resolves the issue, you will need to contact your crowdstrike support vendor for assistance.

This post should also help:

switching Crowdstrike to kernel backend means you can leave it enabled.
