Symptoms

The 'tmsh show apm license' command shows that the current established session count is much larger than the current active session count. In the extreme case, current established session count can reach the maximum allowed, and the system reports the ERR_TOOBIG error in the apm log. err tmm3[12351]: 01490581:3: (null):Common:00000000: Access stats encountered error: SessionDB operation failed (key: tmm.license.global_estab_stats.f26de3c7, ret: ERR_TOOBIG).

Impact

There is no impact to user sessions. Only the connection counts are impacted.

Conditions

This counter out-of-sync period happens right after failover and lasts for five minutes.

Workaround

None.
