From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Stability problems with a Raspberry Pi ZeroW2 (lemmy.zip)

Let me start with, that I am running Raspberry Pi servers since the first Raspberry Pi was released more than a decade ago. Only problems I ever had until now, where dying SD-Cards with the first generation of RPIs. Since them I only buy really big high quality SD-Cards and I have RPI(4) servers running 24/7 for years w/o any troubles.

For a new project, I am running a web service on a Raspberry Pi ZeroW2 with an Apache reverse proxy on the same machine. Memory usage, even under load, is a maximum of 100 MB. This RPIZW2 simply dies after a few days, and I have no idea how debug this problem.

More details of the RPIZW2:

Uses Raspbian configured via Ansible to be an exact replica of my RPI(4), only Apache and a webservice were added
Quality power supply (original RPI hardware) and literally plugged to the same electricity circuit as the RPI(4)
The webapp is just a 'hello, world' with the current time and my internet connection is not fast enough to be DOSed
Monitored memory usage etc. for several hours and found nothing out of the ordinary
fail2bann is active and running
SD-card has several unused GIGs of free space and is same brand/quality as the one in the RPI(4)

Anyone experienced something similar? Has anyone an idea how to approach debugging this problem?

I am not sure that there is a better place at Lemmy for this kind of question than here. I'll happily move this post to another place, if it is not appropriate here.

I've owned and deployed a lot of pi, every model, and in my experience when I have similar instability as you described its related to the sdcard. Either the sdcard itself or the tray soldered to the pi. I had one pi that would corrupt the sdcard without fail after 2 months and I played with bending the sdcard metal tray inward a little to help press the card better into the contacts and the problem went away. Try fiddling with the sdcard holder or different sdcards.

Thank you for the tip, I'll check it out, if the Pi runs unstable again. Just surprised, it sounds that it happened often to you... Since I upgraded to better sd-cards, I never had sd-card trouble again for nearly a decade now. (And I am constantly running multiple Pis 24/7 as servers)
