Re: Help:General protection fault in Linux?????? (It's the swap!)

[Alexander Woodby <awoodby tir com>]

Just tried mkswap (after swapoff) and get

mkswap: warning: truncating swap area to 130752kB
Setting up swapspace, size=133885952 bytes

Why is it truncating the swap size?  I seem to remember an older version
having the swap size limited to 130M but not any more, what's the deal?

TIA,
