Low Application Memory

The Logix Designer application is low on application memory for one of these reasons:

Total Free - the amount of free virtual memory is above the application limit.
Largest Free Block - the largest free block of available virtual memory is above the application limit.
Number of Free Blocks - the number of free blocks of virtual memory that are over a size limit is above the application limit.
Total Allocated Memory - the combined amount of committed and reserved virtual memory is above the application limit.
