Sophos Home Firewall is rebooting multiple times a day.

Hi,

I'm using Sophos Home Firewall (now version SFOS 18.5.4 MR-4-Build418, but tested also on latest version and situation is the same) virtualized on Proxmox (7.2-11).

Sophos is restarting very often (by itsefl). How to check what is the reason? Which log should I read?

It can reboot after 6h or 30 minutes.

Hi, check that you have fixed and exclusive use of CPU, RAM. Also have you disabled power saving on the motherboard? Ian

Proxmox VE is a very stable platform, so I would guess this has other reasons. Can you exclude external factors form your power source or LAN?

It was working with OPNSense for over 3 months without any issues. I decided to move to Sophos and issues begin.

So are you running virtualized or non-virtualized at the moment?

If situation does not change running either way, I almost certainly say it does not derive from the sophos OS.

I was using OPNSense (Bare Metal), then switch to Proxmox with OPNSens (Virtual).

Next I decided to move to Sophos (KVM Virtual Appliance) and have issue with it.

I tested on newest version 19.0.1 MR1 and 18.5.4 MR-4.

I added Zabbix monitoring to the system and I don't see any CPU/memory peaks.

Can you remove Proxmox and run the Sophos "Software-Installer" on bare metal?

Not possible, Sophos not supporting Intel i225 card.

Problem was with additional OPNSense VM. VM has 1 LAN interface only and was used as CA. After shut down this VM sophos is working stable.
