Hello,
I have a Xiaomi Mi Router 4A Gigabit Edition with Openwrt 22.03.5
It's an unshielded one
It's running Unbound and wpad-wolfssl installed instead of wpad-basic and dnsmasq, and irqbalance
Sometimes it randomly restarts, and I don't see high ram or cpu usage
Mem: 52240K used, 68484K free, 1244K shrd, 0K buff, 15640K cached
CPU: 2% usr 2% sys 0% nic 89% idle 0% io 0% irq 6% sirq
So I set up Visual Syslog to collect logs and try to understand why it happens
Aside from the normal sta connected/disconnected etc the only thing that happens before the restarts is this:

I do not understand this, are those cryptic warnings the reason for the restarts? Thanks.
