I am running Fedora 25 on a reasonably recent beefy computer. This is a
Intel(R) Core(TM) i7-5960X CPU @ 3.00GHz with 16 cores and 64Gb RAM on kernel
4.8.11-300.fc25.x86_64. However, every so often when either memory usage rises to more than 20Gb or CPU usage is quite high the computer bricks and I have no idea why.
I would like to understand why this happens and have some logs to find out the issue. How can I setup my computer to understand what is the problem next time it happens. (By the way,
memtestx86+ shows no problem in RAM)
One idea I was would be to ssh into the machine from another terminal and have a
journalctl --follow command running but I am wondering if there's a better way or another suggestion.
