Yes, you can restart all processes using SSL.<p>However, I&#x27;ve often been in situations where I reboot anyhow, because rebooting means I&#x27;m 100% confident the old code is gone, whereas if I try to get clever and avoid the restart, I&#x27;m significantly less confident. Depending on how hard it is to validate the security bug, that can be a problem.<p>Plus, for much of the past 20 years for many computers, if you&#x27;re going to restart all services, adding in the last step for rebooting doesn&#x27;t add all that significantly to the downtime. Server-class hardware often have things that make that not true (stupid RAID cards), but for everything else you were often only adding, say, 25% for the actual reboot.
