Hi Greg , Previously we were running Mesos 0.27 on Rhel6 and since we already have one c group hierarchy for cpu and memory for our production processes I'd we were not able to merge two c groups hierarchy on rhel6. Slave process was not coming up. Now we have moved to Rhel7 and both mesos master and slave are running on rhel7 with c group implemented.But we are seeing that mesos UI not showing the actual memory used by framework.
Any idea why framework usage of cpu and memory is not coming in UI. Due to this OS is still not killing the task which are consuming more memory than the allocated one. We have verified using top command that framework was using 2gB memory while allocated was just 50 mb. Please suggest.
