Probably the weirdest hardware issue I'd ever seen

Hi all,

I had the pfSense build running with a 3days+ uptime until yesterday morning it was dead in the water. All case fans + Noctua fan were spinning but it would not POST; keyboard LEDs wouldn’t light up – nothing.

Even the Asus mobo’s error LEDs didn’t show any issues. As a last resort I pulled the RAM out. RAM error LED came on.

Replaced RAM. Boom, it posted.

Has this ever happened to you?

What kind of monitoring/alerts do you have in place?

What do you mean?

Is there anything in place to notify you if you get scary messages from the kernel or SMART or anywhere else?

For instance, here is a snippet from a FreeBSD kernel log that prompted me to replace a ram module. In this case, it was a FreeNAS system which will automatically report these things if you set up email alerts.

Do you see anything suspect in dmesg?
