Hi,
I have a pizero running on stretch - "Linux cam 4.14.79+ #1159 Sun Nov 4 17:28:08 GMT 2018 armv6l GNU/Linux".
It is connected to a VGA monitor ( not hdmi). A usb wireless keyboard is attached to the usb port.

It all works fine. Was able to login to console and work. Started tmux and a few panes. I was running various programs including raspberry pi camera web interface.It was running fine for more than a day. I was running some terminal commands to watch process, tail files and also htop. I would constantly see console written to.
On the second day, I noticed that console monitor was frozen. htop was frozen, journalctl -f etc were frozen. I tried typing with the keyboard and no response on the console.
I thought the OS crashed, However, I could ssh and everything was working fine. I tried reconnecting the monitor and tried a wired usb keyboard but no use. Though, could ssh and all was well.
Could someone please explain what might be going on. Why the monitor and the keyboard were frozen.
Thanks
K
