We are seeing the same, looks like a memory leak to us but we assumed that it might be related to our way we monitor the routers. vSphere 5.5. We also increased the memory to 1gb but it only "takes more time" to fill. To us, it seems to be related to SSH connections or logins, and we found a potential related issue on github indicating a memory leak in systemd-logind https://github.com/systemd/systemd/issues/8015 We were able to force the memory going down very quickly (200MB withing minutes) by using, 2 parallel executions of the following commands ssh in into a VR from the managemnt host (Sometimes a ctrl-c and restart is required to enforce it) while true; do ssh <router_ip> 'free'; done with the following config # cat .ssh/config IdentityFile /var/cloudstack/management/.ssh/id_rsa Port 3922 ControlPath ~/.ssh/master-%l-%r@%h:%p ControlMaster auto Host 10.100.10.* StrictHostKeyChecking no UserKnownHostsFile=/dev/null Regards René
