RE: Memory staying in cached status -- Possible Memory Leak



I like to use a utility called nmon. (I know that there are other
utilities but cannot think of them atm.) It can profile the resource
usage of a machine but I do not remember if it will actually output the
memory usage of the programs running.

To use top to output to a file. 
"top -b -n X (where X is how many times you want it to run)
> /someplace/somefile"
A "top -b" will run until the it is stopped and will update every 3
seconds.
