After you created an ECS bound with an EIP on the management console, the ECS creation was successful but binding the EIP failed due to insufficient EIPs. Although the Task Status showed that the ECS creation failed, the ECS was displayed in the ECS list. The results of the ECS creation task were inconsistent.
If the ECS is created but EIP binding failed, the task failed. However, the ECS you created is temporarily displayed in the list. After the system rolls back, the ECS is removed from the list.
