In an ACI fabric, the vPC IP address is managed by the dhcpd process. Sometimes when deleting vPC/vPC domains, the clean up does not complete. The fabricExplicitGEp managed object gets deleted, but the corresponding fabricVpcResource managed object does not get deleted. As a result, upon creating a new vPC pair, the dhcpd process might assign the same IP address that the deleted vPC had. The dhcpd process will crash while assigning a different IP address for second time because of this bug.
