[GLLUG] How worried should I be ...

[John Hearns]

As Martin Broosk says run memtest.
You can run the user space memtester on circa 90% of the RAM.
Ever better download https://www.stresslinux.org/sl/
Format a USB stick and boot from it. Then run the memtester utility there.

On a server I would advise to use the iDrac or BMC and get a list of the
hardware events also.
