Hi all,
my server runs fine but i'm wondering if the memory usage is in a normal
state.
the server is a VAlinux 2200 series with dual PIII 800 Mhz and 512 MB RAM.
software is linux debian 2.2r2 , qmail 1.03 , standard qmail-smtpd and
qmail-pop3d server with vpopmail 4.8.9 and imp/webmail
here is some screen dumps of TOP ** and PS -AUXW qmail processes:
258 processes: 256 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: 15.8% user, 10.0% system, 0.0% nice, 74.0% idle
Mem: 523804K av, 521596K used, 2208K free, 0K shrd, 249844K buff
Swap: 248968K av, 0K used, 248968K free 42580K cached

** sorted by mem usage and showing main 3 processes using memory: OSPFD,
SNMPD and apache-ssl ( for IMP/Webmail)
as you can see near all physical memory is used and nothing from the swap
part. the cpu seems very low loaded and a lots of sleeping procs !!!
