Fixed In Version: openstack-tripleo-common-9.4.1-0.20190119050434.261de49.el7ost
Doc Type: Bug Fix
Doc Text:
Prior to this update, controllers with a large amount of RAM could experience soft lockups. This would occur due to memory pressure as the dentry cache on controller nodes would grow continually. Now, prior to doing a curl statement in the container health check, the `NSS_SDB_USE_CACHE` environment variable is set to 'no', which prevents cache growth.
