Hello All,
My question was:

One of the accounts using the application on our system was the culprit.
By the end of the day, the system reclaimed its memory after that account
shut down its session and restarted.
I used the command ps -eo ucomm,pid,vsize,rssize suggested by Michael Matthews
to compare the before and after. I have been using syd and along with monitor
to monitor my systems. My conclusion is the processes that showed up on
the listing from the ps -eo command before and then didn't show up after
the system had more memory caused the memory to go low. The values for vsize
and rssize were not extremely large or different than that of the ones
brought up by other accounts using the same application. Other than that,
the system had nothing abnormal running that would take up that much memory.
Perhaps I am VERY wrong, but Unix is not robust enough to provide utilities
to pinpoint the exact problem. %^)
Thanks to the everyone who responded to my question. All of the responses were
helpful.
