I have to ask what OS/hardware/ISP are you running? What procedure are you using to prep for the OS patching (we stop client sessions/all admin processes - do a full DB backup - halt the server)
Our offsite replica server is RHEL 7 on Dell R740xd with 192GB and 3TB SSD with the DB currently at 2.3TB used. We patch monthly and never had it take more than 15-minutes from OS reboot to ISP server being available! On Mon, Mar 11, 2019 at 11:41 AM J.
