In response to Per olof Ljungmark <p...@intersonic.se>:
What is a good way to find out how memory is used? Have a 6.4 box where
memory is used by something but I fail to see what is using it - tried
different switches to ps(1), tried the stat tools but a big chunk of
memory does not show at all.
A proper tool for analyzing memory usage "live", this is a production
box?
I've always been able to get what I need from top. You can do -o res to
sort by resident memory usage, which helps.
ps will sort by memory usage when given the -m flag. Also check ipcs -a to
see if there are any sysv shared memory segments hanging arnound. If you
don't see anything using the memory, where are you seeing that "something"
is using it?
...and here is top output after I stopped Postfix, slapd and Cyrus-IMAP.
