Plot is freezing or even rebooting entire system! Ubuntu 20.4

Hi, please help. After the plot starts, it goes to phase 1, and ofter 80 or so buckets it freezes the system or its shuting the machine down and rebooting. It,s Ubuntu 20.4, CHia 1.1.1.5, I am not using GUI.

The logs show:

My first feeling is a hardware problem. Memory or hard drive. Run tests to rule them out.

yeah, run mprime / prime95 overnight, and memtest full pass.

Seems you’re right. I run phoronix memory tests suite and it crashed the system exactly like it did. Swapped the dimms for another set, so far it runs ok.

Thanks for your help.
