Details if related
To calculate the buffer pool size, we need to accumulate all reserved memory and than subtract the sum from total available memory. In the current implementation, one part hasn’t been added to reserved memory, which causes the buffer pool size larger than it should be.
To fix it, we need to add it to reserved memory.
