Rig Keeps Crashing with no error on system logs


I need help figuring out why the past two days my rig has been crashing for no apparent reason, when I look into the logs I don’t find any indicator as to why.

Specs :

GPUS : 5 x RTX 3060s @ 0 2350 135 ~ KAWPOW
Other GPUS (Ethash): GTX 1080 @ 100 1400 135 (Eth Pill)
GTX 1070 TI @ 100 1200 110
RTX 2070 @ 100 2400 110

Temps : 45~60C @ 45~60% fan-speed.

Mobo: H110 Pro BTC+ ASRock (P1.10 06/20/2017)
CPU: 4 × Intel® Core™ i5-7400 CPU @ 3.00GHz AES
PSU : 2x 1200W HP Server PSU.
Connected directly to my 5G Router.

Logs :

The rig doesn’t shut off, but the whole system crashes. I doubt it got to do with internet/Power outage, as my windows rig kept mining during the time my HiveOS was down.

What I suspect is T-rex KawPow and my 3060s stability or HiveOS server URL. as it was mining perfectly fine with T-rex Octopus and my server URL set to Amsterdam.


Same issue, did you solve it?

What do you get when running the command:
grep -a error /var/log/syslog | tail -n 10

Can someone help me to find out what’s going on with my rig? Sometimes rig is working for few hours, sometimes it’s turning off or hanging after 15 mins.
