Opal memory at 90%+ usage right off boot

I got a Opal router with only the latest firmware, but yet my memory is pegging out at 90+ % even right after a reboot. Anyone know if this is normal and how do I fix it? I’m only using stock multiwan with failover and tailscale. I keep having to reboot it every 6-8 hours.

Why do you having it to reboot?

Because the data speeds are a crawl and have packetloss / high ping. rebooting it fixes those issues but it’s starting to happen between the 6-8 hour range.

I’m using mwan failover with priority in this sequence
4G Tethering via wan port
4G tethering from a second device over USB port.
WWAN via DSL wifi.
