Re: [TCLUG:5069] out of memory

[Chris Kesler <chris@pconline.com>]

My ISP's server has this line in it's /etc/fstab.

/dev/sda3               swap                    swap    defaults        0 0

If you don't already have a line that looks similar, just copy that line
to your /etc/fstab. It doesn't matter where it is in the file, as long as
it's on a line by itself.  You will need to change /dev/sda3 to reflect
the location of your swap partition. 

If that line is correct, you can run 'swapon -a', then check /proc/meminfo
again to see if it worked.  That command will enable swapping on all swap
devices listed in your /etc/fstab (which is probably just one).

I hope it's as simple as that.  If not, I can think of a couple other
things to check for.  You might want to use fdisk to check that your swap
partition has type 82.

If the above stuff checks out, but you still don't have your swap space
after a reboot, your 'swapon -a' command may be missing from your init
scripts.  On my RedHat system, it's rc.sysinit.  You can just add 
swapon -a
to the file, on a line by itself, if it's missing. 

Good luck,
Chris
