Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: The readiness probe for Elasticsearch uses curl with https. curl uses NSS for crypto. NSS uses too much file system cache. Consequence: The file system cache dentry grows too large too fast. Elasticsearch and the node may become unresponsive. Fix: Set the flag NSS_SDB_USE_CACHE=no in the readiness probe to workaround the NSS behavior. Result: No undue growth in the dentry cache for Elasticsearch is seen.
