The following is still an issue for some CENTOS8 (CloudLinux 8) vms running cpanel whenever the guest agent is enabled. Just tested again today and it crashed the VM requiring a qm unlock and qm stop before disabling the agent and starting it again. I know this isn't new, but wondering if any upate is available.
