Description: Number of memory free operations.
What is memoryNFrees?
The total count of memory deallocation (free) operations since boot. Comparing allocs vs frees reveals memory leaks if allocs consistently exceed frees. Example: if allocs is 1,000,000 and frees is 950,000, the system may be leaking 50,000 blocks.
