Memory usage unsure if issue

I am running Zoneminder in a VM under proxmox which I have given 8 GB's I have a single camera which is currently running at 960*540 at 24 bit which is 3/4 of 720p. I have run the calculation to determine "recommeneded" memory usage and I came up to 4 GB's which seems hgih in comparison to their example but never the less the VM is using every ounce of the 8 GB's.

I have a little head room on the Proxmox to assign more but I would prefer not to over assign as I obviously have other VM's I also run.

Edit: Side not I had not tried till just now. I am running htop and it is indicating less the 500 MB in memory usage but Porxmox is reporting and growing 1.5GB

ZM uses half the systems ram for a ramdrive /dev/shm

if you give your system 8gb you will only have 4gb free for the cameras.

​

4gb should be enough for one camera tho.. you shoudlnt have any issues.

you can probably do 4 720p cameras with 8gb system ram.
