Won't reboot, SD card error?

My R-Shake (actually, a “Boom”) went off line about a month ago. I could not access it remotely so I had to retrieve it and remove the microSD card and have a look. In the /var/log/kern.log file I find megabytes of lines like the below. Is it fair to say I need a new micro-SD memory card? Any way to prevent this from happening again?

To follow up my own post, it seems pretty clear that the SD card was my problem. It was a SanDisk Ultra 32 GB. I bought another card “SanDisk 32GB MAX Endurance”, flashed it and everything seems to be working again, for now. This did give me the opportunity to check out the inside of my sealed-up 8" cinderblock containing my station, which had been sitting outside in all kinds of weather for over a year. Absolutely nothing to report, happily enough. There was a small drain hole in the bottom, stuffed with copper wool which I think discourages various life forms. The heat of the Pi and the PoE transformer kept the interior temp a few degrees above ambient, and the humidity near 50% according to the Temp-RH sensor I included, and from the pristine interior appearances this was in fact true. I have run various less-well-sealed instruments in outdoor enclosures, with much worse results after a year of humidity (mold, fungus, spiders, ants, snails, bees, etc.!)
Photo shows the enclosure on a workbench, partially re-assembled.

Hello jbeale, and welcome back to our community!

Indeed, your hunch was correct. Something was going on with the old microSD card (probably some corruption), and I would have advised you to try a new one too.

Your installation is remarkable, to say the least. Great job!
