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.


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


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


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.
