It has happened now a few times and I am not able to understand how to fix the "problem".
My RPz(W) is connected to my WAP. (Linksys WRT 1900acs)
The RPI is headless.
Every 18 seconds - or so - it sends an "I'm alive" signal back to a central machine.
A few times now I see the LED on it going crazy. Flashing like mad.
I can still PING the device, but can't ssh into it as I usually can.
The only option is to unplug the power.
How can I find out what is going on?
To the best of my knowledge it doesn't have exposure to the internet.
I have no ports forwarded, or stuff like that.
Thanks in advance.
