Symptoms

Prior to expiration, the age of persistence entries is reset to 0, thus retaining the persistence entries forever.

Impact

Retention of persistence entries leads to eventual low memory conditions, performance degradation, and traffic outage or restarting of some daemons.

Conditions

-- Persistence is configured. -- A mirroring IP address is configured.

Workaround

Although no reasonable workaround exists, you can clear the persistence table to reclaim leaked memory.

Fix Information

Persistence entries are no longer retained beyond their expiration.
