System Resource Allocation
Each option that is installed in the drive requires a percentage of the available
system resources. Some options configurations can exceed the available resources
of the main control board processor. If 90 % of the available system resources is
reached, an F19 Task Overrun alarm results, which indicates that system resource
utilization is excessive.
