If you know which process you wish to monitor, you could use ps to track
its size:
  ps v <pid>

You can also use the following to monitor the X process, as well as the
three other largest processes (by memory usage):

  # Output some information about the X server process (cpu usage,
memory usage, etc)
  ps auxc <X pid>
  # Output the same information about the top three largest (based on
RAM use) processes
  ps auxc | grep -v "<defunct>" | grep -v -w X | sed -e "1d" | sort +5
-6 -rn | head -3

And if you have it, the "svmon" utility can be used to monitor memory
usage.  You can use it to monitor a process, or memory in general:
svmon -P <pid>
svmon -G

Hope this helps you out.
