Public bug reported: Openstack version - pike Installation process - multinode kolla
We are frequently facing ssh connection loss on our VMs which are running in our production environment. RAM memory usage on our controller nodes becomes low because of which memory automatically shifts to swap. Moreover we checked the CPU utilization of neutron-l3-agents by running docker stats command. Neutron-l3-agent cpu utilization gives lots of spikes varying from 25% to 250%. We have also verified all the services of openstack and all the services are running fine without showing any errors in the logs. However ssh connections on all the VMs gets dropped after 5-10 seconds without giving any error. Could you confirm us the exact reason why we are facing this issue ? ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
