Certain conditions can lead to excessive memory consumption. Excessive buffering results in performance drop, connections being dropped, and Out-of-memory core errors.
This might result in performance drop, connections being halted, and out-of-memory cores. Performance and stability can be impacted as well as full traffic-outages.
This can occur after a long period of time, such as a month or more.
The command 'bigstart restart tmm' on the standby unit will clear up the condition.
Memory usage has been improved for certain categories of connections that are not yet fully established.
