ASM is only supposed to request a Full Sync if there has been a Manual Full Sync request, or if an incremental / auto sync indicates that the state is inconsistent with that of its peers. The system was mistakenly requesting a Full Sync on every config change in an Auto-Sync, Full Sync group even when it was in a consistent state.
Noise on the network, extra CPU usage, Policy Builder restarting on receiving peer.
A Device Group is configured with Auto-Sync, Full Sync, and ASM enabled.
Disable "Full Sync" on the device group
The system no longer requests a Full ASM Configuration Sync on every full auto sync in a device group.
