The ps command doesn't have a good number to display for the kernel idle
PID. If you really need to understand what's going on, I probably can dig
through the data structures that ps is examining, figure out why it has a
bogus value, and help you understand, but suffice it to say that for that
particular PID, the number is meaningless.

hello!
"VSZ" means "Process virtual address size" .You should check "RSS"
that
means " Real memory (resident set) size of the process (in 1024 byte
units)".
you can enter the following command:
ps -e -o rssize -o vsize -o pmem -o command|grep idle.
Good Luck!

Hi
Appears to be confusion as if you give the command ps auxwww
it will show in following order.
USER PID %CPU %MEM VSZ RSS TTY S STARTED TIME COMMAND.
So per your output
1) VSZ will be 524MB i.e is virtaul pages
2) RSS i.e resident pages in real memory will be 20M
3) %MEM shows how much real memory is used i.e 4% .So your total real memory is around 512MB
4) LAstly kernal idle is the name of process and the process is not idle as seen by the status R i.e it is in runnable que.
regards

Subject: I:U: kernal memory usage can be seen by vmstat -M command
hello
one more update : or you can say one more mail to read because as such you will get too many mail on the subject.
If you are worried why kernal is mapping so much memory give command vmstat -M
You can reduce kernal memory use by reducing n number of parameters to minimum requirement.Though it is not worth it as kernal memory will really grow dependent on your free memory availablity.
sorry again to bother you with one more mail.
regards

%MEM refers to RSS and 20M/500M is 4.0%.
Best wishes,
