Use this command to sort everything:

UNIX95= ps -e -o vsz,pid,args | sort -rn

This will show the largest memory users at the top of the list. Note that shared memory cannot be logically assigned to any specific process as it is shared. ipcs -bmop will show shared memory usdage.

I have a general script for performance data collection. I believe the memory portion might give you at least a starting point.

As mentioned, VSZ is Kbytes. This is one of the more useful metrics in ps but requires the temporary setting of UNIX95 to make it work. The man page for ps has this info. I've attached a really useful script called viman--allows you to browse man pages with vi which is a lot faster that using more or pg.
