Stability problems with 9.04 64bit quad core

[Kiernan Holland]

Did you get the 64-bit kernel? Cause I'm not sure the 32-bit kernel can
address more than 4 gigs.

Also your swap needs to be at least 1.5 times your real memory. So you have
6 gigs of ram, you need a swap of 9 or 10 gigs. It probably scaled your
memory down because you didn't allocate enough swap, the swap is part of the
virtual memory, and the more swap you have, the more virtual memory you will
have. Like if you have 10 gigs, you will have 6 gigs real, and 4 gigs
virtual. That's what permits you to work on large images in GIMP and juggle
bunches of programs. It's not so good for audio applications though. You
probably can turn it off.

There is also a way to make it so that swapping of pages out to the storage,
happenbs less frequently. But I forget where that information is in the
configuration files.
