Out of Memory" error on a Service Area Network Analysis

Note:
For analysis of Service Area problem sets, severe memory exhaustion can often result from the Service Area solver creating a traversal result that is too large to hold in memory. In Network Analyst Service, a memory leak occurs each time the service is requested to produce a map image or a legend graphic image. 

Note:
The Network Analyst Service Area solver can be made to 'chunk' the processing behind the scenes to complete very large analysis tasks using only standard memory configurations.

Note:
Memory is allocated from a large pool of unused memory area called the heap (also called the free store). Since the precise location is not known in advance, the memory is accessed indirectly, usually via a pointer reference. The precision algorithm used to organize the memory area and allocate or de-allocate chunks is hidden behind an abstract interface and may not use a fixed method.
