You can ofcourse always update, but wait until later to reboot.
But the update isn't securing the server yet.
And delaying the restart could perhaps cause unexpected issues one might not relate back to the Kernel when a reboot is done later in time.

The latest available kernel 3.10.0-714.10.2.lve1.4.79.el7.x86_64 from CloudLinux 7 is bootable fine under Xen version 4.7:
Code:
[root@vps1 ~]# uname -ir
3.10.0-714.10.2.lve1.4.79.el7.x86_64 x86_64

[ 0.000000] Xen version 4.7.Hello,
Las weekend we updated our OpenVZ nodes to the latest patched CentOS6 Kernel RHEL6 042stab127.2. After updating the kernel, we are seeing some big load spikes on a couple of nodes.
All vps servers running on our nodes are centos6, have directadmin as control panel and are managed by us for our clients. We have seen the following strange issues:
- On one node we had to disable clamav on all vps servers because of huge CPU spikes. All of the vps servers would have clamav running simultaneously, consuming huge amounts of CPU and driving the node load above 200 and making almost everything inaccessible.
- On this same node we have had to change the directadmin nightly tally time inside each vps because load would spike above 100 when this process was running on all vps servers simultaneously.
- On another node, we have seen some big load spikes when csf firewall runs a directory check.
This is what we have been observing during this week. The normal load doesn't appear to have changed on our nodes after the new kernel was installed, but it appears that some processes are causing huge load spikes.
Has anyone else seen strange things happening on their centos6 servers after installing the latest kernel?
Regards!
