3.9.3 terminating miner, mining XMR

[xmrminer1]

I get this error message every single day with the nano miner 3.9.3, mining Monero XMR. Sometimes it happens after a few hours, sometimes it happens after a few minutes:

2024-Nov-02 18:30:38: Monero - SHARE FOUND (CPU, nonce: 353f69ad).

I'm trying to figure out what's causing the miner to terminate on its own, and quite frequently too. I'm using an AMD Ryzen 9 3950X with a water cooler, RAM is G.SKILL F4 DDR4 3600 C16 4x16GB - 32GB DIMM DDR4 clocked @ 2133 MHz, motherboard is a ASUS ROG Strix X570-E Gaming ATX. No idea what causes this.

Earlier this year, it would work just fine for days on end. Now, it shuts itself off all the time. Is the CPU getting too hot? Do I need to tweak any settings? Any advice or help is appreciated.
