hi guys, 
	using Armbian 23.02.2 Buster with Linux 5.15.93-sunxi on a NanoPi Neo Core LTS.
 
	 
 
	I configured cron to do a daily reboot at 00:30.
 
	 
 
	Every 10-20 days the system is becoming unresponsive unless I do a power cycle.
 
	Where should I begin to investigate this issue?
 
	 
 
	Thank you
