  "message": "Cache: added watermark to reduce IO load when keys_zone is full.\n\nWhen a keys_zone is full then each next request to the cache is\npenalized.  That is, the cache has to evict older files to get a\nslot from the keys_zone synchronously.  The patch introduces new\nbehavior in this scenario.  Manager will try to maintain available\nfree slots in the keys_zone by cleaning old files in the background.\n",
