Hello! I try to install nodejs+mysql+nginx app. VPS: 80$ (4 cores, 4gd ram) Ubuntu/Debian I have nodejs app, what runs behind nginx Setup is pretty common: nodejs, pm2, nginx, mysql, autobackup, ufw, nothing special.
But for some reason, server randomly freezes. i CANNOT access to server even through digiocean admin VNC console: its grey, no symbols. No ssh, http reaction. Problem was very same on clean ubuntu and deb installation. Prior to freezes, there was some [UFW BLOCK] messages, no kernel panic messages.
Could you please advice, how to diagnose random freezes?
Thank you in advance!
