I am running OMV5 on a Raspberry with 4GB. When I boot up everything (Encrypted drives, mergerfs, SMB, VPN, Docker and 5 containers incl NGinx and Nextcloud) my system uses 0.6GB ram. If I let it run for a few days the Ram fills up to 3.9GB and never comes down again. I have even started to increase my Swapfile but all gets used up. It seems Debian or OMV never releases memory.
Is there a way to force a ram flush?
Has anyone seen the same behaviour?
