NTP bursts from FortiGate firewalls

The FortiGate problem is still present, though the number of affected clients is slowly dropping. [It’s been almost two years!] The burst duration is typically 10 seconds or less.

Miroslav recently pointed to a systemd bug . The key indicator seems to be "fractional part wrapping around 232 milliseconds " I’ve seen this bug as have several others.

Can you forward a pcap?
