When using parent policies with learning enabled in an auto-sync device group, in some use cases deleting an ignored suggestion on a parent policy will cause a full sync to occur. This can cause unexpected delays in configuration being synchronized between peers, and in the event of repeated instances in quick succession could fill the /var partition
ASM configuration requests a full sync which can cause unexpected slowness in config synchronization and may fill the /var partition if done multiple times in quick succession. A full /var partition can lead to bd cores.
1) Device Group with ASM and auto-sync enabled 2) Parent Policies with learning are in use. 3) Ignored Suggestions are deleted on the parent policy after they have 0 suggesting children left.
