[~jharshman] Can you investigate those settings to see if these are good enough for you or we need more/better/other things? was (Author: dahn): clear. there are some other knobs to turn: vm.memballoon.disable in the agent.properties file on the host(s) and cluster.memory.allocated.capacity.notificationthreshold and cluster.memory.allocated.capacity.disablethreshold.

Sometimes an instance > with X amount of RAM provisioned will be started on a host that has X+a small > amount of RAM free. The kernel OOM killer will eventually kill off the > instance. Has anyone else seen this behavior, is there a way to reserve RAM > for use by the host instead of by Cloudstack? Looking at the numbers in the > database and the logs, Cloudstack is trying to use 100% of the RAM on the > host. > Any thoughts would be appreciated. > Thank you, -- This message was sent by Atlassian JIRA (v6.3.4#6332)
