Issue
Today, I have a RPI3 which is under Rasbian. Power wire are on 2.5A and temperature are around 39/40°C (I had a fan on it)
My problem is: My Raspberry Pi 3 is connected to my box and it's use as a web server. For now it works "perfectly". But sometimes - and this is the problem - the Pi is not responding.
I mean that all my website are "offline", I can't connect via via SSH locally and the only thing I need to do is to "force" reboot it by remove the wire. After that everything is OK.
Actually, I don't know where to look for. It's can't be hardware issue because of the wire and the temp right ?
So is it a software issue? If yes, How can I know which froze the device ?
Solution
Plug in a monitor and look what happened. Maybe you see a kernel panic or kernel oops on the screen, maybe you can just login on the terminal and look what happened (maybe the network is down for some reason).
If everything freezes without visible error on the console, add more logging. install a munin, use verbose logging for all services you're using and read the logs after the freeze and look at the munin graphs what happened (i.e. if there is a memleak, you probably see it in the memory graph before everything freezes).
