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 ?
