Description:  The lowest number of free message anchors reached during processing.

Usage:  Use this element in conjunction with the fcm_num_anchors configuration parameter to determine the maximum message anchors utilization. If MA_free_bottom is low, you should increase fcm_num_anchors to ensure that operations do not run out of message anchors. If MA_free_bottom is high, you can decrease fcm_num_anchors to conserve system resources.
