Recently, my server started having these random shutdowns (power offs).  I've enabled syslog logging and noticed a constant stream of segfaults.  It's too early to conclude these segfaults are causing the server to power off but does

 

Anyhow know what could be causing these segfaults?

Start by running memtest.

Thanks. I found which docker container is causing the segfault.  

 

As for the randon power down,  I notice the server will power off when we're playing a video game in Windows10 VM.  I've stopped the VM to see how long the server will remain up.    Running memtest is a good suggestion - thank you.
