Add cgroup memory limits to jenkins_slave. Add cgroup memory limits to the jenkins_slave module. Nodes including jenkins_slave::cgroups will have the jenkins user's processes limited to use only 90% of the nodes available memory. There are two exceptions to this. The jenkins process run by the jenkins user will not have its memory capped. Also there is a soft memory limit of total physical memory * 0.75. If there is memory contention the jenkins user processes may get only 75% of available memory.
