ps versus top VSZ and RSS

[Mario Olimpio de Menezes <mario@curiango.ipen.br>]

Hi,

	I'm trying to find what should be the best limits to my users
and so I'm inspect VSZ and RSS from various users. 
	Today I found a strange output from ps:

USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND
mlalic   17348 99.1 32.6 241104 84216 ?      R    11:26   5:15 lapw1
mlalic   17361  0.0  0.1  1136  496 ?        S    11:26   0:00 csh -f
mlalic   17363 99.3 32.7 241100 84404 ?      R    11:26   5:15 lapw1

and from top:

  PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME
COMMAND
17363 mlalic    18   0 84400  82M   576 R       0 99.5 32.7   3:37 lapw1
17348 mlalic    15   0 84212  82M   576 R       0 97.2 32.6   3:37 lapw1


	So my question: what is the real VSZ lapw1 processes are using?
	Maybe better: are VSZ and SIZE the same	thing? Am I
misunderstanding here?
	
	BTW, my system has 2 CPU's, that is, SMP. Do I need special
ps|top for correct info? Where to get them?

# ps -V
procps version 2.0.6


	Thanks!
