Hello All,
I have a RB750 running v6.35.4 and its working fine after reboot in several hours,
but sometimes working unstable need to reboot it and get working fine again.
Screenshot of Ping:
I used following function on my RB750:
- PPPoE Client
- L2TP Client with IPSec
- Firewall Mangle (Mark Connection Packet) [14 rules]
- IPv4 Route (Routing Mark and Static)
- Queue Tree and PCQ
When RB750 get unstable cause:
- IPv4 ping unstable but IPv6 fine
- IPv4 packet drop Intermittently but IPv6 fine
System Resources:
- CPU about: ~70% [on download file] <15% [normal]
- Memory: ~ 8-7 MB
Here are rules of Firewall mangle:

I guess this issue caused by firewall rules or Room temperature (~31 ℃)

Anyone know how to fix it? THANKS.

THERE ARE THE SAME PROBLEM
This problem is only shown on version 6.29 or later, I think is made by FastTrack (start supported from 6.29).
Now, I’m downgraded RB750 to 6.25 and watch network stability.
