Hohe Load und Probleme mit Internetverbindung (PPPoE/VDSL)

[robgnu]

Hall Zusammen,

ich habe seit einigen Wochen ein paar Probleme mit einer OPNsense. Es stellt sich wie folgt dar:
Zunächst "bricht" die Internetverbindung weg und nach kurzer Zeit kommt die Verbindung zurück. Allerdings ist die "Load average" anschließend nicht mehr bei 0.xx sondern konstant über 3, teilweise sogar über 5. Im LAN ist das Arbeiten quasi nicht mehr möglich und es hilft nur der Reboot der OPNsense. Ich suche schon eine Weile nach der Ursache, komme aber nicht wirklich weiter.
Zur Konfiguration:
- APU2 mit OPNsense 25.1.7_4
- Dual WAN:
 - Interface WAN: vorgelagerte FRITZ!Box Cable von Vodafone
 - Interface VDSL: Vigor Modem mit Telekom VDSL
 - Die Gateway-Group ist auf "Fallback" gestellt, Telekom-VDSL ist primär.

Die OPNsense taggt auf VLAN7 und stellt die Verbindung absolut zuverlässig her - inkl. IPv6 und /56 Prefix Delegation. Die gleiche VDSL-Konfiguration benutze ich bei anderen OPNsense Installationen auch.

Inzwischen habe ich sogar ein paar Logs. Gestern lief die OPNsense einwandfrei, heute früh war die Load wieder hoch. Und zwar genau seit 5:57 Uhr. Das steht in den Logs:

Die Load lag bei >3 Anschließend habe ich versucht über Interfaces -> Overview die VDSL-Verbindung vom VDSL-Interface neu aufzubauen. Dadurch ist die Verbindung komplett unterbrochen. Die Load stieg auf >5 und VDSL blieb offline. Hier das Log dazu:

Anschließend blieb mir nichts weiter übrig, als die OPNsense neu zu starten. Jetzt läuft alles wieder normal. Ob das jetzt eine Stunde gut geht oder 1-2 Tage stabil läuft, ist nicht vorherzusagen.

Hat jemand eine Idee was ich noch probieren kann? Ich bin kurz davor, die Hardware und das VDSL-Modem zu tauschen.
