Question

Debian/Ubuntu VPS freese for no reazon

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!

When trying both Debian and Ubuntu did you do a rebuild of your original droplet or did you delete it completely and create a new droplet?

The lack of access to the console is concerning. Your droplet sees the console as it’s local keyboard and display so the lack of access there could point to a serious issue. I would recommend opening a ticket with our support team if you have not already so they can investigate further.
