I am a happy user of Raspbian on Raspberry Pi. I have some services there like VPN, Plex, Pi-Hole, etc.
Every 1-2 years it starts showing "segmentation fault", when running some commands. I need to take the card out, reflash it with a backup image and put it back in.
I know other people experience that too. Why is this happening? Is there something I can do to avoid it? Would mounting the SD card in r/o mode help?
