The persistence cache records accumulate over time if the expiration process does not work reliably. The 'persist' memory type grows over time when multiple TMMs are sharing the records.
Memory pressure eventually impacts servicing of traffic in multiple ways. Aggressive mode sweeper runs and terminates active connections. TMM may restart. Traffic is disrupted while TMM restarts.
- Non-cookie, persistence configured. - Multi TMM box - Traffic that activates persistence is occurring.
None
Persistence records are now reliably expired at the appropriate time.
