Machines shutting down by themselves

[Uondaime]

Machines shutting down by themselves, every day I have to access proxmox to start the machines. Any solution for this?

What do you mean by "machines"? Nodes or guests? If you are talking about guests you should search the syslog for OOM messages. If VMs/LXCs are shutdown its most of the time the OOM killer that kills processes because your host is running out of RAM because you overprovisioned your RAM.
