I have a server in my #homelab that I #selfhost in my literal garage. It has a funny problem. When it gets too cold (and right now it is 11ºF, -11ºC in Virginia), it crashes. 🤦‍♂️

I bought a replacement a few weeks ago and I moved the last VM off of it last night. This morning I woke up and found that it was crashed....again. So I hit the power button turning it off, and said in my best Darth Vader voice:

"you have failed me for the last time."

@paco I can only imagine it's a condensation issue at that temperature. -11°C isn't very low for any of the components in that machine, especially when you consider the self-heating will be bringing it higher. so you might have to watch out for that on the new machine too.

@gsuberland Ambient air temp is about 66ºF / 19ºC.

Good call on checking humidity/dew point.

@paco @gsuberland but also, sometimes there's a contact that will break when temperature changes expand/shrink some part past a threshold. I've only seen this firsthand in the other direction though.

@regehr @paco the contact pressure should be more than enough to handle that unless it's a very sudden temperature change. but even then I've seen folks splash LN2 on running boards during extreme overclocking benchmarks and they continue working just fine.

@gsuberland @paco it was a PCI board where I saw this happen. could have been a bit bent, have a damaged contact,. or whatever
