Last month I did a clean installation of Jessie Lite after realizing NOOBS took way too much space on my 8GB card, and as of last week I've been using it primarily as a DHCP server with pi-hole until I get some more stuff on there. This has been the first time I've had it on 24/7 instead of turning it off when I'm done by the end of the day.
Problem is, twice now it has simply stopped responding after about 3 days of uptime. Specifically:
- The green LED stays on for about 3-4 seconds, off for 1, and back on, again and again.
- Attempts to ssh do nothing, Putty shows an error (which I think was “Software caused connection abort”) and JuiceSSH on my phone only gets so far
- Plugging a keyboard in directly and attempting to enter commands, Ctrl+Alt+Del, etc, also does nothing.
Both times I've had to unplug power and it booted back up just fine.
Any ideas? And where should I be looking to troubleshoot this?
