Persistence records accumulate over time due to expiration process not reliably taking effect. The 'persist' memory type grows over time.


Memory pressure eventually impacts servicing of traffic in a variety of ways. Aggressive sweeper runs and terminates active connections. TMM may restart. Traffic disrupted while tmm restarts.


-- Non-cookie, non-mirrored persistence configured. -- No high availability (HA) configured or HA connection permanently down. -- Traffic that activates persistence is occurring.
