As the Title says if a high amount of Data is send for a period of Time OpenWRT just reboots. I first noticed that my DB always crashes when uploading many files to Nextcloud and at the same time my Network connection stopped working and first i thought it was a Nextcloud issue as always but after standing by the Raspberry Pi i saw that it completely rebooted.

Raspberry Pi 5 Model B Rev 1.0 8GB
Linux version 6.6.44 (builder@buildhost) (aarch64-openwrt-linux-musl-gcc (OpenWrt GCC 13.3.0 r27107-44b6df3184) 13.3.0, GNU ld (GNU Binutils) 2.42)

I also don't think its a power problem because i use a 65W Lenovo Laptop Charger and this thing should easily handle the Raspberry Pi and Overheating also not because i have a big Active Cooler that starts spinning at 35 C°

If you need any logs please ask

Edit: I stand by the Raspberry Pi to see what exactly happens and it looks like it just reboots for some reason

Yes, but still we don’t know if the psu actually work properly.

And what controls the cooler, 35° where is that measured and what is the CPU actual temp?

The Raspberry Pi 5 is somewhat special in that it requires 5 volts at 5 amperes. It does not utilize the Power Delivery functions in your power supply.

Your 65w Lenovo laptop charger is limited to 2 amperes at 5 volts. Your Pi 5 sees the power supply as a 10 watt unit. That may not be enough, depending on what devices you connect.
