Symptoms

If a sync-compatible pool is created and given pool members, pushing that sync operation will cause the member count to be incorrect on all other devices.

Impact

The number of pool members will be displayed incorrectly at various points (GTM statistics, the ltmPoolMemberCnt SNMP variable, and the GUI).

Conditions

This only affects device groups where incremental sync is in use.

Workaround

Perform a sync between the creation of the pool and the pool members.

Fix Information

The pool member count is now always calculated accurately, even across configuration synchronizations.
