We need to keep "Automatic Updates" enabled on our cPanel servers as that allows to get rid of any security hole that may have been recently found and patched by cpanel. We take care of Server Security and OS related security from our end but cpanel updates cannot be disabled.
Even though the some functionalities change in your control panel but its not something so major that you need to learn the control panel from the beginning. Changes are very minor and it takes no time to understand those.
Becareful with CPanel release 10.9.0 - 57 release..
Theres a corker of a bug in it relating to the management of Parked / Addon /Sub domains.
On my previous host everything was all jumbled up with subdomains showing in addons, addons showing in subdomains....right ole mess it was and they said there was nothing they could do until CPanel released a fix. Problem was you couldn't delete anything..
As per my knowledge you have a VPS and we will need to check why cpservd is failing on your VPS. cpservd checks working of all services and if any service goes down then it will restart that service automatically.
If cpservd itself fails then there wont be auto restart for other services if any service fails. Contact our VPS Hosting support team to get this sorted.
