+++ This bug was initially created as a clone of Bug #1302401 +++ The metadata cache expiration timeout was hardcoded to 15 seconds in versions older than kilo (OSP7). In kilo a new configuration option was added: 'metadata_cache_expiration', Time in seconds to cache metadata; 0 to disable metadata caching entirely (not recommended). Increasing this should improve response times of the metadata API when under heavy load. Higher values may increase memory usage and result in longer times for host metadata changes to take effect. introduced in: https://review.openstack.org/159264 This config option should be backported to OSP5 in order to provide the same flexibility and avoid premature cache expiration in cases where the metadata is highly static. --- Additional comment from Red Hat Bugzilla Rules Engine on 2016-01-27 13:30:20 EST --- Since this issue was entered in bugzilla without a release flag set, rhos-8.0? has been automatically added to ensure that it is properly evaluated for this release.
