Ubuntu stops services suddenly, SSH, Caddy Serve

[Niraat]

Good afternoon, I have a LXC Container Ubuntu version 20.04.6 LTS tty1, occasionally at different times ubuntu stops the services, I noticed that it is stopping the SSH and Server Caddy (are what I currently use), when I want to start them I get an error (attached photo), I have to reboot and the proxmox console marks me an error


client connection: 127.0.0.1:49090
error reading from pty: Input/output error (os error 5)
TASK ERROR: command '/usr/bin/termproxy 5900 --path /vms/101 --perm VM.Console -- /usr/bin/dtach -A /var/run/dtach/vzctlconsole101 -r winch -z lxc-console -n 101 -e -1' failed: exit code 1

I have to restart the server to get it working again

Can someone help me, thanks

Do you have enough memory?
Does the filesystem have free space?
Is the filesystem still mounted read/write?
A few things to start with

¿Tienes suficiente memoria?
¿El sistema de archivos tiene espacio libre?
¿El sistema de archivos todavía está montado en lectura/escritura?
Algunas cosas para empezar

Yes, it's very rich, attach the Summary.
