We lower the default for the parm vm.swappiness The default is 60 and we mostly set this to 5 now.
To see where it's set now; cat /proc/sys/vm/swappiness Change it; echo 5 > /proc/sys/vm/swappiness Update the /etc/sysctl.conf file to keep where you want it ... 20, 5, or even 0 ... Hope this is some help...

I understand it's function, but the double allocation of these pages is causing my low memory alerts to trip. I can remove the swap copy with a swapoff/swapon. Is there a more elegant way to remove? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
