This is less trivial than it seems to be. A process can have several types of memory allocated:
1) real memory
This is real RAM the process uses.
2) virtual memory
This is real memory as above plus allocated but swapped out memory. This actually is what the
vsz metric in the
ps output shows.
3) shared memory segments
Sometimes several processes use some memory segment collectively. I.e. database software Oracle, DB/2) makes extensive use of this feature. Use the
ipcs command to find out if the process owns shared memory segments.
I hope this helps.
