In my experience random reboot problems are usually related to the sd card. standard logging setups kill the card faster than you'd think. dd the existing install or rebuild the server.
time to test your disaster recovery strategy!

Thank you and u/irmadlad for the suggestion. I ordered a new SD card and will just clone the current one. I'll probably get to it this weekend and let you know if it worked out.
Fingers crossed.
I went with Alpine Linux for hosting because of this. I like up how my light setup runs completely in RAM, saving the SD card for a while.
I really tried to use a “usb” install for a long time but could never get kernel upgrades (and some other packages) to work correctly.
These days I do a “sys” install but mount /var/log and some other directories to RAM.
I'm an expert at nothing, but I'm going to guess and watch the thread: Power/Under voltage or SD corruption. I'm favoring the latter.
Reason being, the logs are pretty normal. I don't see anything that would portend a crash. So it could be that when the RPi crashes requiring you to pull the plug, it hasn't had a chance to write that to the logs. I know, back in my RPi days, I had a lot of issues with SD corruption.
agreed.
voltage problems would most likely result in odd errors in syslog.... random controller grumbling messages, resets, etc.
