help on sin

Hi,

anybody, plz,

explain me exactly:
what are mean each of numbers in “sin -P appname” command output.

e.g. (it is real)
io-net 7536698 52K 5677K 208K 772M 19483
what is mean: 52K
what is mean: 5677K
what is mean: 208K
what is mean: 772M
what is mean: 19483

You can see a the number “772M”. it is nonsense!!!
but my box has 64M RAM and 128M swapfile size
what is mean? BUG?
or is it means just not a some kind of memory size?

Thanks!

Hm… try “pidin -p io-net mem” for a bit better break-down of what all
the values mean.

By comparing numbers between “pidin -p process mem” and “sin -P process”
for a couple of processes, I’ve come up with:

e.g. (it is real)
io-net 7536698 52K 5677K 208K 772M 19483
what is mean: 52K

This is the code space for the process. (io-net)

what is mean: 5677K

This is the data space for io-net, including all data associated with
shared objects that io-net has loaded.

what is mean: 208K

This is the amount of (thread) stack that has been physically allocated.

what is mean: 772M

This is the amount of virtual stack that has been reserved for all
the threads in the process. This number seems a bit high. For my
case, this is about 1200K.

what is mean: 19483

I don’t know what that one means, but it seems to increase over
time for some processes.

The 772M does look very odd, but it isn’t a measure of real RAM,
just of virtual. It would be interesting to see the “pidin -p io-net mem”
output for io-net when the OS is reporting this much virtual stack for its
threads.
