Memory consumption of tmm slowly increases.
Device may fail over to another unit in the high-availability (HA) configuration.
This occurs only when a session is terminated in policy evaluation phase, e.g., a client lands on the logon page and lets it times out. You can determine whether this issue is occurring by checking for memory usage as 'session' is expanded to 4 GB.
To recover from this issue, restart tmm. Note: Traffic will be disrupted while tmm restarts.
Memory consumption of tmm no longer increases when a client allows the logon page to time out.
