Yes, it´s only ;-) up for 16 days since I added the extra ram. > Has it been running for months or something? Do you run >netscape on it a lot? I start netscrap once a day when I come to work, and close it when I leave. History has told it´s lessons about leaving netscrap running overnight... > Are there many zombie tasks or inordinately >memory-hungry tasks running? No zombie task, but once per night I run a glimpseindex over all my mails (~600 meg) but I´m restricting mem usage to ~ 32 megs for it. The largest process at the moment is X with ~ 13 megs. Is there any possibility to find out what process´s pages are swapped out? Basically all the ram is just sitting there waiting to be used, but that won´t happen for a few weeks, because the java-application which will need it hasn´t arrived yet. >>What can I do to increase the amount of ram used for buffering/caching >>so that only 5-10 % are left free?

I have ~ 75 processes running, mostly sshd´s, telnet´s and bash´s, nothing out of the ordinary. >>If I´m not mistaken the whole swapped-out pages should acutually fit >>into the free ram, so swapping here seems rather, umm, less than >>optimal? > >Well - theres always stuff that gets swapped out because it hasn't been >needed for ages, imagine if you had a scsi card driver in your kernel >(ignore modules) that either didn't find its hardware, or you have a scsi >card that you haven't used since the system has booted.

Well, I´m running the stock kernel, but everything else is in use over the day. >>The system is an up-to-date potato >>Linux cruncher 2.2.15 #1 Thu Jun 1 10:47:16 EST 2000 i686 unknown > >Its not up-to-date if its not running the latest kernel in the range - >2.2.17 at the moment :) Hmm, the war uptime vs. kernel is usually won by uptime here ;-) , but all the other packages are up-to-date as of yesterday. (That´s why I´m running 2.0.3[6,8] kernels on some other boxes) tnx, &rw -- / Ing.
