The system has a number of miscellaneous kernel memory allocations too. Lets call those "misc kernel". Also, some of the categories you mention overlap with others, ie. pages belong to multiple of the categories at once. Active + Inactive + free + misc kernel = MemTotal Buffers + Cached + SwapCached + misc kernel + process memory not accounted for in the previous categories + free = MemTotal > What should i add that i can account for the MemTotal memory? > in this and on per process basis. A per process basis is difficult too, because processes often share a lot of memory. Eg. almost all processes in the system will be sharing the same C library. -- "Debugging is twice as hard as writing the code in the first place.
