Indeni is reporting kernel table 'cptls_server_cn_cache' as almost full on Security Gateway
Symptoms
  • Indeni is reporting cptls_server_cn_cache as almost full on Security Gateway. (The integration of Indeni with Check Point management servers and gateways allows network security operations teams to continuously validate their environments’ configuration against an ever growing set of Check Point device knowledge.)
Cause

The cache saves mapping between IP+Port to CN (Certificate's Canonical Name) and a flag if the CN is valid. The table will go up to 10,000 entries and be cleared automatically to make room for new entries.
