Comment 14 for bug 1354479

I was able to reproduce this bug on vanilla MOS 5.1 with 3GB of RAM on controllers.

 Attached is the output from Top command.

Environment:

Ubuntu + HA mode
Neutron+VLAN
2 controllers
2 computes + Ceph OSD

Ceph Ephemeral volume enabled
Murano enabled
Use qcow images turned off.
Other settings - defaults.

Strange, but this issue does not appear of I do the same deployment to CentOS.
