1. The current active sessions, current pending sessions, and current established sessions counts shown in commands 'tmsh show /apm profile access' and 'tmctl profile_access_stat' become zero after failover. 2. The system posts an error message to /var/log/apm: 01490559:3: 00000000: Access stats encountered error: SessionDB operation failed (ERR_NOT_FOUND).
The current active sessions, current pending sessions, and current established sessions counts of profile access stats remain zero after failover.
This issue happens when the following conditions are met: 1. The HA configuration is running a release prior to 11.5.3 HF2, 11.6.0 HF6, or 12.0.0. 2. A standby unit is upgraded to version 11.5.3 HF2, 11.6.0 HF6, or 12.0.0. 3. Failover is triggered.
Upgrade all devices in the HA configuration to the same release and reboot them simultaneously.
The current active sessions, current pending sessions, and current established sessions counts of profile access stats now report correctly after failover.
