Longview - ntpd active connections
In Longview under active connections I see 20 active connections for ntpd constantly.
Is this normal behavior for openntpd?
IMHO, you don't need ntpd(8) at all in a Linode VPS. The OS that hosts your VPS gives its (probably ntpd(8)-derived) time to your VPS. All you have to do is set the timezone.
If you want to run ntpd(8) or chrony(8), check /etc/ntp.conf or /etc/chrony/chrony.conf and make sure you don't have multiple NTP servers defined. You shouldn't need more than two…a primary and a secondary. There will be a connection for each server defined.
