Minimum system requirements (1707-1)

I’ve been experimenting with the current distro and find that it won’t install on a 512MB machine (the installer runs out of memory). I can install it with 2GB and then reduce the size of the VM to 512MB and it seems the services barely fit in this footprint, swapping a bit. My conclusion is that 1GB would be about the minimum memory allocation for any practical, small use. I don’t see any minimum requirements posted. Could anyone comment further?

Upstream RedHat and CentOS recommend 2GB since version 6 last I checked.

It also belongs to that what you are using with freepbx. in our case we need at least 3gb ram to hace a stable pbx. Thing like ldap user sync need a lot of more ram for a short time during the tasks.
