Pi stuck after a couple of days - Any idea?

I am running a regular Raspbian stretch lite on my Raspberry Pi 3 b+ where I installed docker and homeassistant/raspberrypi3-homeassistant and marthoc/deconz images.
After a couple of days I find the Pi stuck, inaccessible adn unresponsive.
I’ve not a monitor attached and I disabled the WiFi power management.
Do you have any idea about why my Pi hanags? It runs stuffs related to HA only.
Thank You for any suggestion


Raspberry use to be picky about the power supply. From the rasp page:

“We have found that purchasing a 2.5A power supply from a reputable retailer will provide you with ample power to run your Raspberry Pi.”

The usual 500ma/1A USB cell phone charger will not do it.

I read that warning so I already had bought an official power supply…

Nice! I learned the hard way :-(.

There’s lots of information in the /var/log folder that will be there after you reboot which may help you track the problem down. I’m presuming you can at least ssh in from another device.

I just looked into syslog but it looked frozen. What file can I check too?

The cmd ‘dmesg’ can give you the latest; I’m not sure if that pulls through a combination of those logs, but it’s usually helpful.
